Daylight Saving Time: the 2007 Y2K

Filed in MiscellaneousTags: Geekery, Technology

As far as tech nightmares go, this one might be worse than Y2K.

The US Congress changed the rules for Daylight Saving Time, starting in 2007. This year, rather than spring forward the first Sunday of April and fall back the last Sunday in October, DST will begin on the second Sunday of March, and end the first Sunday of November.

Growing up in the then-non-DST-observing Indiana, I still find the whole DST process foreign enough that I don't have a set routine. So for me, I make the change when I'm told, and move on. However, many of today's advanced consumer electronics have programmed algorithms for DST - and reprogramming these devices might be impossible, potentially requiring manual changes four times a year. Worse, as with Y2K, legacy computer systems and software may not account for the new changes properly, leading to potential - and unknown - consequences.

Microsoft has established a help center to deal with the change as it impacts their products.
