Heads up - March 11th is coming! That's the new date for the daylight savings time switchover. The DST switchover is the new Y2K, only without the sexy acronym.
Seriously, if you want your boxes to behave right on March 11th you should probably do something about it.
If you happen to run Fedora Linux, you can probably get away with doing:
# Check your system zdump -v EST5EDT | grep 2007 # Patch it. yum update tzdata # Confirm it worked zdump -v EST5EDT | grep 2007
