After upgrading my Ubuntu Dapper Drake 6.0.6 LTS server from 4.0.2 to 4.5.1 now I see the following in replied messages:
"Sent: Monday, February 12, 2007 8:41:01 AM (GMT-0600) America/Mexico_City"
Before the upgrade Zimbra would append "GMT-0600 US/Central" instead. Now, I realize the GMT offset is the same, but I would like the correct timezone nonetheless. The server's timezone is central time as it has always been, how do I fix the Zimbra timezone? Thanks.
