There's a glibc component (you should be fine running WBEL3) and the time zone files...
The stuff under /usr/share/zoneinfo is the TZ info for everywhere, BUT /etc/localtime is
the TZ file for YOUR SYSTEM.

Pull /etc/localtime from another (working) system and see what it does for you...

The test of a fixed /etc/localtime is: 

[crhea at kaizen ~]$ /usr/sbin/zdump -v /etc/localtime | grep 2007
/etc/localtime  Sun Mar 11 07:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 CST isdst=0 gmtoff=-21600
/etc/localtime  Sun Mar 11 08:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Nov  4 06:59:59 2007 UTC = Sun Nov  4 01:59:59 2007 CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Nov  4 07:00:00 2007 UTC = Sun Nov  4 01:00:00 2007 CST isdst=0 gmtoff=-21600

(I'm in CST/CDT, but the key is the dates).
