Daylight Saving Time Already?

Yes, readers, it's that time of year already.  Hopefully all of our North American readers will just wake up an hour earlier on Sunday morning and not worry about server logs having an hour of "missing" data, since all of them are running their server clocks set to GMT, right?  Of course!

For those interested in further information on Daylight Saving Time, see these relevant Wikipedia articles:

For everybody else, sorry about the missed hour.  You'll get it back later this year.

One other thing, a reader last year pointed out something obvious.  If you have a bedroom clock, VCR, or other device that automatically adjusts for Daylight Saving Time but has no way to update its firmware to the new dates of changeover, simply advance the time zone to the one that is east of you for the next few weeks until we hit the old day that is burned into your firmware (first Sunday in April.)  Then set it back to the true time zone you are in.  Some call this the "Y2K7 Problem."  Here's another Wikipedia article for your reading pleasure:
