Good morning! Check your clock: If you’re in the U.S.A. — or most of it, anyway — you lost an hour last night. Now the rest of the world will be playing catchup, so all those time differences you have filed away in your head will be different for at least the next three weeks. After we had finally gotten in sync with the U.K. — after years of being a few weeks out of sync — we’re back to square one. I’m in EDT, so it’s just four hours to London today. I had a phone conference scheduled with Jerusalem for 9 a.m. this morning and instead of there being a seven-hour difference, it was only six. But they were expecting to do the call at 4 p.m. their time, so I could have slept in. Which would have been a good thing, since of course even though there were reminders around, I didn’t remember until last night, and since I watched Saturday Night Live, that meant I didn’t get to sleep until 2, “new” time. If I’d remembered, I would have Tivo’ed it. My computer still thinks it’s EST–yours too, probably. And then three weeks from now it’s going to jump ahead. We’re not going to be able to trust the timestamps on Internet sites and email for a couple of days either, until everybody’s Web folks get around to fixing their clocks or all our contacts re-set their computers. (For the sake of full disclosure, LOL, the timestamp on this blog post is an hour earlier than I actually posted it.) Anyway, if you want to check and see who’s on what time around the world today, here’s one good roundup. FYI Europe (most of it, anyway) changes the clocks the last Sunday in March, and Jerusalem does it on March 28. — Mary Hunt, editor, eFlyer
