In 2005, US Congress changed Daylight Savings Time so that, beginning in 2007, it begins on March 11 and ends on November 4.
Most servers have already been updated, but since you definitely want to check, here's the command to do so:tzdump -v /etc/localtime | grep 2007That should print out a list that confirms that DST is set to begin on March 11, and end on Nov. 4.
If it doesn't, well I suppose you need to get an updated tzdata package, or a patched zoneinfo file for your timezone. Ask your sysadmin.
