Tip o’ the Week 388 – Crossing Time Zones

Another dip into the annals of ToW, dusted down and spruced up – this topic was first covered in #301, though the topic of time zones has also featured in #280, #244, #120, #26…

When moving between countries, one of the tricks the traveller needs to decide is how to handle the switch of time zone. Do you set your watch to the destination time as soon as you board the plane, or only when the pilot announces, in his or her ever-so distincive pilot tone, what the local time is on arrival?

Also, do you wait for your phone to pick up the destination time zone automatically, or do you set it manually? If you have a Fitbit or other wearable, do you want it to pick up the time from your phone or do you force it on departure? Decisions, decisions…

Frequent travellers tend to have pearls of wisdom on how to deal with jet lag – like get your mind in the destination time zone and keep it there (ie. If you’re out having dinner after arrival, do not keep saying that it’s really 4am; it’s 8pm now and you can’t go to bed for at least another two hours), or get the sun – or even a bright light – on the back of your knees. All we can cover is how to handle the crossing of time zones using your PC…

Outlook – whenever an appointment is created, its date and time are recorded as an offset from UTC, and the time zone it’s due to take place in is also noted. If you’re creating meetings or appointments which are in a different time zone, like travel times, then it may be worth telling Outlook by clicking the Time Zone icon in the ribbon, and then selecting the appropriate TZ – especially useful if you’re moving between time zones during the appointment itself, and don’t want to run the risk of horological befuddlement.

If you’re booking a load of appointments in another time zone – eg. you’re working in another country for a few days and creating appointments with people in that locale – then it’s even worth switching the TZ of your PC whilst you do the diary-work, to save a lot of clicking around in setting the appropriate time zone specific to each meeting.

The best way to do this would be to show your second time zone in the Outlook calendar – in the main Outlook window, go to File | Options | Calendar and select the second one to show; when you’re ready to switch between your local TZ and the remote one, just click the Swap Time Zones button to switch the PC (and Outlook) between the different zones.

Windows 10 – In the Settings | Date & time menu, there’s an option to tweak how Windows deals with time and time zones – some of which might be applied by policy and therefore greyed out for you. Like other phone OSes, Windows 10 – even on proper computers – has the option of setting time zone automatically.

If you’re going to use the time zone swapping in Outlook as per above, then it’s worth disabling the automatic mode as Windows can get itself properly confused; the default time zone will change, and Outlook will end up showing the same time zone for both primary and secondary.

Using the old fashioned Windows control panel time settings applet, you can choose to show a second time zone in the clock on the system tray – in the Date & time settings, look to the right and you’ll see Add clocks for different time zones.

There’s a nice Alarms & Clock app in Windows 10, that shows a map of the world with your choice of locations, and the moving daylight line so you can see what’s happening around the globe. A good alternative to that exec boardroom display nonsense, that you might expect to see gracing the wall of your average corporate hot shot.
