Tip o' the Week 454 – Time Zone Tumult Ahead
You may be affected by upcoming changes to time zones, as much of the northern hemisphere moves out of Daylight Saving Time and back to winter, which for is happening over the next couple of weeks.
Many Southern Hemisphere nations have already moved into “summer time”, though a few will make the transition on 4th November.
Europe, most of Mexico and parts of the Middle East will move out of DST this weekend, but most of the North America and the Caribbean will “fall back” the week after. See the list of places that currently observes DST and when they transition.
This can play havoc with people’s electronic calendars; systems these days generally take notice of time zone changes pretty well and that means the relative times of meetings are preserved, though what this does mean is that a 9am meeting organised in Seattle (and therefore hosted in Pacific Time) will be 5pm for attendees in London this week, but it would be 4pm GMT the week after, then back to 5pm after that, as the US moves clocks back.
This topic was covered 3 years ago in ToW #301, and most of the tips contained therein are still valid today.
Maybe future generations will stop the winter/summer time flip-flop effect altogether (Californians get to vote on whether to join their neighbours in Arizona, by staying on the same time zone all year, and the EU may stop the practice of changing clocks too). In the meantime, for a few weeks a year, those of us who deal cross-border may need to think a bit more about what the time is in our neighbour’s locale.
If in any doubt, make sure you add another time zone to the time scale on your Outlook calendar view, so you can see at a glance what the time is in other regions.
One further innovation since the last time this topic was aired, is that Outlook now lets you show a third time zone in calendar if you so desire.
