This isn't exactly true. You can keep your hardware clock on local,
and you can tell Linux to use local time (keeping it from messing
around). Linux does not set my hardware clock to GMT at shutdown, it
sets it with local time, which is what I want because I use ntpdate to
update date/time every time I bring up a net connection. Sure,
setting up GMT is the Unix(TM) thing to do, but why bother? It knows
my timezone, handles daylight savings automatically, and it stays
accurate thanks to ntpdate; nothing wrong with using local time.
