There appears to be a problem in TZ referencing the tztab file. What are the permissions on /usr /usr/lib and /usr/lib/tztab? They should look like this:
# ll -d /usr /usr/lib /usr/lib/tztab
dr-xr-xr-x 25 bin bin 8192 Oct 24 2003 /usr/
dr-xr-xr-x 39 bin bin 16384 May 30 14:45 /usr/lib/
-r--r--r-- 1 bin bin 12794 Nov 14 2000 /usr/lib/tztab
Another way to test is to specify a different TZ value on the command line:
TZ=MST7MDT date
Mon Jun 20 08:41:02 MDT 2005
TZ=PST8PDT date
Mon Jun 20 07:41:37 PDT 2005
These should each produce different times with the chosen timezone shown at the end. If you see EDT for all of these, access to the tztab file may be disabled or TZ was never exported for subprocesses.
And that may the problem: your shell's set command reports on the local variables, but env reports on exported variables. TZ is not there. Find where TZ is set for this user. It should always be set in /etc/profile as:
. /etc/TIMEZONE
VERY IMPORTANT: there is a dot (period) in front of the TIMEZONE shell script. This makes sure that the current shell runs the script and not a subshell. Without the dot, a subshell runs the script, the setting is made and then the subshell goes away and the setting in the local shell (including export) is never made.
