As we noted earlier in the week, Europe changed time this past Sunday, so your offset with European counterparts may change once again.
Here’s an idea to think about while we’re talking about time zones, however: Does the U.S. mainland require four time zones in this day and age? Allison Schrager wrote recently that the U.S. should drop Daylight Savings Time and cut down from four to two time zones.
Whether or not you believe that should be done, it’s an interesting reminder of how we got to having time zones in the first place, as well as a discussion of the various issues involved. Meanwhile, if you’re traveling this weekend, perhaps this is the weekend for a manual alarm clock. I never trust my phone to wake me properly for a Sunday morning flight when the time changes.
