Because of the Commonwealth Games, Daylight savings doesn't finish (or is it start?) for another week. So the time now is still 11.37 (instead of 10.37). On the 2/4/2006 the time will go back 1 hour.
Most operating systems need a patch to cope with this.
For Windows you can download a patch through Windows Update (note it is not a critical update it is a critical update).
Mac OS X Tiger uses can update to 10.4.5
For Linux and FreeBSD users (should also work for Mac OS 10.3, 10.2 etc) there is a great blog post here about how to update your system:

EDIT: Even though this webserver has been updated my post still shows 10.41. I'll need to look into this.
