Unix Timezone Settings

[gaf at blu.org (Jerry Feldman)]

Actually, most Unix systems to not have a provision for the machine time 
to be local time. Linux, on the other hand, is many times dual booted 
with other OSs (Windows and OS2) such that it can use local time as 
the machine time. I keep UCT (GMT) on my laptop which is Linux only, 
but local time on my desktop where I have Windows (which I use only to 
flash my linksys router).
