I wouldn't call it a patch. A patch is code to correct an anomoly. Not everyone wants their clocks to update (it could have very dangerous or even deadly repurcussions in some situations) therefore the lack of the feature is not an anomoly.
If you require an automatic update, you can easily insert your own code. The code posted by sheirj will do the trick.
You could also do a search on the forum on daylight savings time for other ways of dealing with it because this subject comes up at least twice a year.
