Timezone problems

[CMRGIBBONS at uqvax.cc.uq.edu.au]

I seem to be having a problem setting our timezone.
When I put the line:
   TZ = "EDT10EST11;78,300"
in our etc/TIMEZONE file the time reverts to GMT.
The examples in man timezone also default to GMT.  We are running 3.2 on a
PI and a 4D/80GT, the 4D/80 being timeslaved to the PI - it keeps terrible
time on it's own!
