641 – What’s the Time, Mr Wolf?

Posted on July 29, 2022 (Updated July 29, 2022) by ewand

Time-telling technology has always been a hot-bed of invention, from the radically precise first marine chronometer in the early 18^th century, allowing more accurate navigation on long sea voyages, to atomic clocks that can measure time with the accuracy of one millionth of a second over 10 years.

Computers and smart phones probably never need your intervention to set the time, except when travelling abroad and you want to manually manage the time zone – if you prefer not to let the machine do that for you. To play with the time settings in Windows, just right-click on the clock in the system tray and choose to adjust from there.

If you’d like to know what the actual time is, maybe after a power cut has blanked the clock on your cooker or you need to adjust because of Daylight Savings Time, how do you know what the real time is? Call the Speaking Clock? Switch on TV news and wait for the clock in the corner to click over one more minute?

Even better than that, check out time.is, a service synchronized with an atomic clock and which purports to figure out how accurate your computer’s clock is compared with the real time. Open the time.is site on your mobile phone and you’re ready for next time you have to set the clock on your video recorder or bedside alarm.

The chronometer (“time” and “measure”) evolved from a ship’s device for navigation and became a byword for a really accurate watch (they even had competitions until the late 1960s for the manufacturer who could make the most accurate timepiece – right up until the Japanese started beating the organising Swiss at their own game, so they took their ball away and went home). Meanwhile chronographs (“time” and “write”) were devices made to accurately measure time gone by, such as at the request of France’s King Louis XVIII, who wanted to know exactly how long his horse races lasted. Early devices actually marked the passage of time on the dial with a pen.

In Windows, you can easily time events or have countdown timers that alert you when your eggs are boiled or it’s time to start working again – look in the Swiss Army Knife that is the Clock app. You can display multiple timers in one window if necessary, make a single timer go full screen (useful if you’re presenting and counting down to getting started) or pop out to a side window.

If you wear an old-fashioned watch, you may have a simple way to measure elapsed time – some will have built-in timers, and others will have a moveable bezel which lets you rotate the zero-marker to where the minute hand is pointing at the start of something you want to time.

If you look at the watch a few minutes from now, you’ll see how many markers on the bezel the minute hand has moved on by – not exactly sub-second accurate but it’s good enough for the “about 10 minutes” type measurement.

You could also reverse the process and set the bezel’s 50 minute marker at the minute hand, so counting down 10 minutes towards the zero marker instead. You do need to keep an eye on it as there’s no alarm.

Contemporary chronographs are analogue watches with built-in stopwatch functions, usually controlled by start and stop buttons on the side. They may count to fractions of a second marked around the edge, and some sport Tachymetre marking around the outside – designed to let you calculate how fast something is travelling as it goes over a set distance, or how far you’ve travelled if you know your constant speed.

It’s hardly red-hot technology, but millions of watches have this fantastically complicated but nowadays basically useless feature. They have to sell wrist furniture somehow.

Perhaps the most over-sold and fantastically-named wrist watch from the 1960s was the now re-issued Croton Nivada Grenchen Chronomaster Aviator Sea Diver – a single device that could be used for so many things as it combined various chronograph and bezel-rotating features in one 38mm-wide watch, billed as a “wrist-sized computer”.

Just make sure you have a magnifying glass handy to be able to read all the tiny markers and numbers on it.

637 – Focus and disturbance

Posted on July 1, 2022 by ewand

Happy New Year! Now that we’re into the second half of 2022, we can look forward to new stuff coming to Windows 11, in the guise of the next update, currently in test with the Windows Insiders and due sometime soon, known as release 22H2.

This new version comes with a bunch of visual and some functional tweaks (which some might argue should have been like that since the release of Win11 nearly a year ago). The Start menu has had some attention, something to be revisited in a future Tip.

One welcome area of deeper integration is a broad subject covered in ToWs passim – the varied ways of managing do not disturb, quiet hours and attempting to focus.

In Win11 22H2, the Focus sessions feature which was previously added to the Clock app has now been tied into the Windows shell more neatly – if you click on the date/time on your taskbar to show the calendar (or press WindowsKey+N to see notifications, which does the same thing), you’ll see a little Focus button with an adjustable time next to it.

Click that and it will launch a new mode of the Clock app which displays a simple control showing the elapsed time on a circle, and clicking on the square in the middle will stop the session. The expand icon on the top left will launch Clock showing the Focus blade, also displaying To Do Tasks, Spotify (if you have it set up) and a history of today’s other Focus sessions.

Settings for Focus have also been placed in the main system Settings app, providing some configuration on what happens during a Focus session (and you can start a new session from there too):

At least for now, there’s still no Teams or Outlook integration so merely being in Focus won’t change your Teams availability status, nor will it switch Outlook into Offline mode as did the old internal-to-MS “FocusTime” app.

The Do Not Disturb feature in Windows 11 also has some rich settings to make sure your machine doesn’t give you notifications at inappropriate times – including a little button next to the notifications list on WinKey+N. If DND is switched on either here or by an automatic rule, you’ll also see a little bell icon emitting Zzs, on the taskbar next to the clock. Subtle yet useful.

Still more focusing options are offered by Viva Insights – that has the ability to proactively book time in your schedule to ensure you can focus, and will silence chats and so on while you’re supposed to be concentrating.

601 – Time and Focus

Posted on October 8, 2021 by ewand

Twice a year, it seems, there’s a ToW article (passim) about the shocking time zone change that is about to hit us. Or may have already – some parts of Australia (NSW) have just moved into summer time while neighbouring areas (QLD) stayed on year-round time. Much of Europe is about to head back into winter time on the last day of October. One week later, most of the US will return to standard time, meaning that the US and Europe will be one hour closer for those 7 days. Arizona will revert to having a single time zone for the whole state.

Many Windows 10 users may have escaped knowing about the app known as Alarms & Clock, and the groovy World Clock which shows a map with pinned locations of your choice, detailing the current time in each.

The cartographically obsessed may note that when compressed into a small window, the exact locations of some pins might look awry, but expand it properly and they’ll move around as you would expect. In the example above, London looks to be in Bordeaux, Budapest has swapped with Bangui while NYC has inexplicably relocated to eastern Peru.

Especially useful when figuring out relativity of time zones and future dates, is the Compare feature which lets you see what the time will be at a chosen point for each of your pinned cities, on a particular date. Take for example, Monday 1^st November, when in the space of one month, Sydney has moved two hours further away from London, yet the Atlantic is temporarily one hour shorter.

Well, the Clock app, as it’s now known – even though it doesn’t actually feature a clock per se, but let’s not split hairs – has been given a UI polish as part of Windows 11, and one additional new feature pane – Focus Sessions. It was shared with Windows Insiders a couple of months back, but is now mainstream for Windows 11 users.

Long-time ToW readers may recall an internal-to-Microsoft app called FocusTime, which let the user run a timer to focus on a given task, while putting Outlook into Offline mode so you didn’t get any new emails, and setting Office Communicator/Lync status to Do Not Disturb so you didn’t get annoying IMs. Well, Focus Sessions in Clock is doing a similar job though without (yet, at least) the integration to Outlook and Teams.

As well as tracking the number of Focus Sessions you have, the app can also let you create and pin tasks with Microsoft To-Do to achieve at a later focus time. One slight grind at the moment is that the app only allows you to sign in with a Microsoft Account, not your ~~Office~~ Microsoft 365 / work identity, so you won’t be able to seamlessly integrate with other task management tools you might already be using, like Outlook Tasks or an M365 To-Do list.

The Focus Sessions feature is newly released and the team behind it is looking into how to integrate with other tools and services, such as the Focus Assist feature in Windows (which quietens notifications, formerly known as Quiet Hours). If you’d like to see improvements or new features in the Focus Sessions section of the Clock App, make sure you go to the Feedback Hub and either upvote existing suggestions or add your own (instructions here). For some more tips on using Focus Sessions, see here.

#571 – Save the Daylight

Posted on March 12, 2021 by ewand

In the Northern Hemisphere, spring feels finally underway – and following a long locked-down winter, it can’t come soon enough. For many of us, even if meteorological spring started nearly 2 weeks ago, the promise of summer starts when the clocks go forward to daylight saving – or summer – time.

If the country or state you’re in observes summer time, then you’re either about to enter (if in the northern half of the marble) or leave it (if southern). To keep us on our toes, this movement back or forth often happens around the world on different dates. To keep us on our toes, some countries have less-than-hour gaps between time zones, and in the past, others have decided to change time zone permanently.

In olden days, some people wore GMT or World Time watches, which allowed the user to tell what the time was in different locations. With the World Time example here, the red arrow hand points (on a 24hr scale) to the current time; when the user rotates the outer bezel so that the nearest location is pointed to by that hand, the other locations listed on the bezel will be aligned with the 24hr number of the current time in those places…

– eg if it’s 2:30am in Iran, then lining Tehran up with the red hand would put both London and Paris at midnight, since they’re both at GMT+1.

eh? In October 1968, the UK decided to move to British Standard Time – GMT+1 – all year round. This particular wristwatch was produced between 1968 and the end of 1971, when the practice was reversed – so for a while, it was correct that London would be in the same time zone as Paris and Rome. Except the watch wouldn’t know when Paris and Rome went into summer time, thus putting them an hour further ahead… oh well, never mind.

There may be trouble ahead

In a global working environment, especially one where everything is done online rather than having people in the same location, the friction of time zones changing has never been more obvious. Usually, you’ll only move through time zones relative to everyone else when you travel – flying across large distances, or maybe just driving across a bridge or dam.

But now, a digitally-oriented meeting can shift its time for some of its attendees, relative to the others – depending on where the originator is based.

The excellent Alarms & Clock app, which is part of Windows 10, lets you pin cities around the world to a map, showing their approximate location (bet you didn’t know Brissie was south east of Sydney?) and what the time is currently, and if you click the Compare icon to the left of Add new city, you’ll see a grid indicating the relative time in all of your pinned cities. You can jump to a specific date, so if you’re planning a meeting with people in different time zones, it might be a good idea to check what the impact of Daylight Saving Time (DST) changes might be.

Those parts of the US which observe DST, are due to move an hour forward this coming Sunday (ie March 14^th). In common with doing things differently to everywhere else, that brings the US (and Canada) one hour nearer most of Europe for the next two weeks, until the end of March. Much of the southern hemisphere comes out of DST the week after that, so by then Sydney will be two hours nearer London than currently.
More info.

The impact of this can be seen in peoples’ calendars, when regular meetings somewhat inexplicably start to clash with each other – if a UK organiser set a recurring meeting for 4pm GMT, that would normally compel Seattleites to be there at 8am, but since they’ll be only 7 hours behind for a couple of weeks, that shifts to 9am in their calendar, potentially clashing with some existing 9am Pacific Daylight Time meeting.

Conversely, a 9am PST / 5pm GMT meeting as created by the person in the US a few weeks ago, would now start at 4pm in the afternoon in London. Great news if that meeting is a Friday afternoon, as it brings beer o’clock one hour forward.

Although Outlook does a pretty decent job of juggling the differences between time zones, there is no obvious way to show what time zone a meeting had been created in (eg show me all meetings that are going to be affected by this shift for the next 2 weeks). A simple trick if you want to check on a specific meeting, is to start a Reply to a meeting you’ve been invited to, whereupon you’ll see the time zone of its creator…

551 – Ticking away the moments

Posted on October 9, 2020 by ewand

Keeping track of time is ever-present in our normal working lives, all the more so during These Difficult Times™, and the subject has featured in many ToW’s passim.

There’s a great little app built-in to Windows 10 called Alarms & Clock, which lets you set alarms on your PC, show a world map with multiple locations / time zones displayed, and also provides a neat countdown or count-up timer.

Using the timer function can be pretty handy if you’re speaking as part of an online meeting, and need to keep a check on how long you have left to go.

You can create multiple separately-controlled timers with different durations & names; so you could have an overall meeting countdown timer, and then a separate one for each participant, if you were acting as the time cop to keep everyone else in line.

The Stopwatch is simply a fast-running counter of elapsed time, and by using the icon on either Timer or Stopwatch screens, you can easily fill the display to help focus on the elapsed or remaining time. Handy if you’re in a physical meeting (remember them?) and are able to display a laptop screen showing the time for everyone.

Those of us who still wear physical, mechanical wristwatches may be passingly familiar with a few features that have existed for decades to achieve the same kind of function, albeit more for individual rather than shared use.

Diver bezel

So called “diver” watches were popularised in the 1960s and 70s, as tough, waterproof and utilitarian. The most striking feature of any dive watch is generally the rotating numbered bezel which goes around the outside.

The simple idea was that when you entered the water (knowing you might have 20 minutes of air), you would turn the bezel so the arrow / zero marker was set to where the minute hand was at that point – meaning a later glance at the watch will tell you how many minutes have passed since.

Lots of other non-dive watches also have rotating bezels or indicators, and can be useful for things other than scuba – when the activity above started at 5 minutes to 10, the bezel was set, and it’s easy to see in a trice that was 11 or 12 minutes ago. Not sub-second accurate, but it’s a simple way to mark the passing of time.

Tachymetre /Tachymeter

Many chronograph watches – which combine the function of a stopwatch and a regular timepiece – have a Tachymetre scale around the outside, yet most people these days will have no clue what it’s for. The basic function of the watch is that pusher buttons on the side will start and stop the movement of the chronograph hand which ticks round to indicate elapsed time.

The deal with the TACHY scale is that if you know a distance – the length of a straight on a motor-racing track, for example – and you time something going over that distance, then you can quickly calculate its speed across the ground.

In practice this is easier said than done, since the TACHY scale reads how many of the <distance> would be covered in an hour at this speed. If the measured distance was exactly 1km or 1mile then it’s an easy calculation – if it took 12 seconds to cover 1km, that would equate to 5km per minute or 300km/h. If the measured distance was a fraction – let’s say the length of the 12-second straight was 150m – then the calculation would be 300 x 150m per hour, or 45km/h. By the time you’ve done that in your head, the subject will be half a lap further on…

Another variant on the theme would be if you know the speed – e.g. you’re in a plane with inflight map display, or passenger in a car on cruise control on the motorway – then you could use the Tachymeter to calculate distance travelled.

If you were cruising at 120km/h, and started the timer, then stopped it when it reached 120 on the scale… (after 30 seconds) – then you know you will have travelled 1km in that time.

Yes, there probably are hundreds of times a month when you need to know exactly this.

Pulsations

Slightly more useful to the average person, some chronographs have a Pulsations bezel rather than a Tachymeter scale, or maybe even have both (since the Tachymeter would typically be used for more than 15 seconds, it’s possible to have one quarter of the bezel represent pulsations and the rest of it be a Tachy).

Watches with Pulsations bezels are sometimes nicknamed “Doctors’ watches” as the utility is to help count a patient’s pulse – the method being you start the chronograph, count 15 pulses and the corresponding number on the bezel would tell you what the pulse/minute rate is.

Smart watches, eh, who needs them when you have space-age timing technology like this?
