Will early DST be a mini-Y2K?

Daylight Savings Time comes early this year (March 11). There's growing worry that computers and digital gadgets will get all flummoxed, ala Y2K. From an AP story:

Software created before the law mandating the change passed in 2005 is set to automatically advance its timekeeping by one hour on the first Sunday in April, not the second Sunday in March. Congress decided that more early evening daylight would translate into energy savings.

The result is a glitch reminiscent of the Y2K bug, when cataclysmic crashes were feared if computers interpreted the year 2000 as 1900 and couldn’t reconcile time appearing to move backward. If banks and other institutions aren't properly prepared, automatic stock trades reportedly might happen at the wrong hour, buildings that unlock at a certain time could stay shut, and airline flight schedules could be scrambled.

I've heard from a few readers on this. One fellow, who works on his company's telephone system, says he's "up to his neck" updating voice mail and PBX systems.

Given that Y2K was such a bust, I can't get too worked up about this. We shall see.
