For our USA and Canada readers, don't forget that the start and stop of daylight saving time changed this year.  You've got one more week to go before you move back one hour.   For those in Europe, you should have moved back one hour this weekend.  Of course, if you keep your watch on Zulu time then this is not an issue for you.



Ken wrote to tell us some interesting facts. This year's change also applies to (most of) Canada, the Bahamas, Bermuda, and the French territory of Saint Pierre and Miquelon as well.  Here's some additional references:

Note also the special case of Cuba:

While Cuban DST started three weeks early this year as per all of the above, it ends this weekend as per old rules, not next weekend.

Ken said that with inconsistencies like that, his province of Newfoundand and Labrador changing its clocks at midnight not 2:00am, etc, it's no wonder it took vendors two, three time zone releases back in the spring to get all the details straight!

If you use or manage Windows Mobile devices, take a look at for more information on patches and workarounds.
