Along a similar theme, my laptop has a little display that shows the
current hardware clock time. At the moment this is set to UTC, so all
times are now 13 hours off (it wasn't so bad with 12 hours off, even
though it is 24-hour time, but now it's getting annoying).

How easy is it to change an existing Linux installation (currently running
Ubuntu Edgy) to make the hardware clock use local time instead of UTC?
Will it still be updated automatically when DST hits? Are there any other
caveats I need to be aware of?
