To the best of my knowledge, just install the right zone files

Time should just jump AFAIK. If all computers are patched, then it
won't matter, as everyone should jump roughly the same time. I can
only see issues if one server jumps way ahead of others, and then you
have time stamps too far into the future for example, which throws
sudo off.

Any "calendar/meeting" software. I'm enjoying watching M$ screw up
everything with their new patches etc etc. Patches get applied, then
that evening critical Patches are applied, and people hold their
breath that all the meetings they had to change the time off, won't
have to be changed back. I won't mention which company, but it was a
fun few days from what I heard.

Depends on how your computer gets it's time. Right now, I'm really
glad all my Linux boxes have the BIOS in UTC time. That way, the
hardware clock doesn't need to change, and Linux can hum along like
normal, with new zone files :D

Hope that answers some of your questions, if not, ask again, and
hopefully someone with more knowledge can answer them!
