Time differential problem

Well it says -0500 when you look at the tomcat logs and the logs for the proprietary cisco software. It looks like it grabs the time when the WCS daemons are started because if I change the system clock to a new timezone, it doesn’t take effect in WCS until I restart it. Also if I change to a timezone without DST then it syncs up with the system clock so it's definitely a DST issue. The only DST settings are for applying to Cisco devices that this software controls. Nothing about setting it for the WCS software itself. It's not a huge issue, if we just have to make a mental note that it won't do DST during DST then so be it.

Here's a snippet from the WCS's bundled tomcat log - - [16/Jul/2008:19:13:34 -0500] "GET /webacs/alarmSummaryAction.do?command=summary&dojo.preventCache=1216253613682 HTTP/1.1" 200 417 - - [16/Jul/2008:19:14:35 -0500] "GET /webacs/alarmSummaryAction.do?command=summary&dojo.preventCache=1216253674344 HTTP/1.1" 200 417 - - [16/Jul/2008:19:15:35 -0500] "GET /webacs/alarmSummaryAction.do?command=summary&dojo.preventCache=1216253735024 HTTP/1.1" 200 417

Likewise here's from its bundled apache: - - [16/Jul/2008:20:15:35 -0400] "GET /webacs/alarmSummaryAction.do?command=summary&dojo.preventCache=1216253735024 HTTP/1.1" 200 417 - - [16/Jul/2008:20:16:35 -0400] "GET /webacs/alarmSummaryAction.do?command=summary&dojo.preventCache=1216253795692 HTTP/1.1" 200 417

As you can see apache's doing -0400 hours whereas the tomcat's picking up -0500. Very strange indeed.

Is there any time zone setting in the Cisco program's configuration? 
It sounds like it may be using a fixed offset to UTC, instead of local system time, or a timezone with DST.
