Daylight Saving Time May Bite the Out-of-Date

Daylight Saving Time May Bite the Out-of-Date
by Andrew Laurence

Beginning this year, Daylight Saving Time in the United States begins earlier and runs later than in prior years. Under the new rules, Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November. Previously, it began on the first Sunday in April and ended on the last Sunday in October. This change was signed into law as part of the Energy Policy Act of 2005.

This change means that any device which automatically changes its clock to match Daylight Saving Time, such as a VCR, either needs to be updated with new rules, or must have its clock changed manually on the affected dates. Apple included the new rules for Mac OS X 10.4 Tiger in the 10.4.6 update. (The 10.4.5 update also updated the Daylight Saving Time rules for changes in Australia and other locations.) Currently Apple has only released updates for Mac OS X 10.4 Tiger.
