What Time Is It? Where?

In general, Europe goes off their Summer Time this coming weekend, a week ahead of the end of Daylight Saving Time in the U.S. On the U.S. East coast, we’ll move from GMT minus four hours to GMT minus five hours at 2:00 a.m. on 1 November, but the Europeans, over their various time zones, will have fallen back an hour a week earlier.

Which means that every timetable for every airline flight between the two continents has to be rewritten twice, not just to account for the time changes, but an additional time to account for the one week in between. Here’s a list of Daylight Saving Time Around the World 2009.
