Timezone issues

Hi all


I am having a problem where some users on one of my boxes display GMT
when the date command is run while other users on the same box display
the correct timezone (Australia/Sydney) EST when the date command is
run. I have checked the users environment variables they do not have the
TZ variable set in both instaces. 

I am a bit perplexed as to what is going on here.  As the man pages are
not giving awayany clues here


OS: version 5.1a pk6  with updated timezone patch. 

local time zone Australia/Sydney

contents of /etc/svid3_tz 
:Australia/Sydney

localtime -> /etc/zoneinfo/Australia/Sydney


Thanks in advance
