My problem is that calendar events occurring in most of October are displaying 1 hour too late in the web interface. Editing the event shows the correct start time and the correct timezone is set for the event, for the user and on the server and client computers. The server is OS X 10.4.11 which has correct timezone data (as shown by zdump), the client computers likewise. In previous years the change to daylight saving in Sydney was at the end of October, and this year onwards it is at the start of October. Somewhere there is stale timezone information and my guess it is in java on the server.
On our server:
java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-164)
Java HotSpot(TM) Client VM (build 1.5.0_07-87, mixed mode, sharing)
There is a java update from Apple which updates to:
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-241)
Java HotSpot(TM) Client VM (build 1.5.0_13-121, mixed mode, sharing)
So I have two questions:
1. Might updating java on the server fix the calendar event display error?
2. Will doing this update have any untoward effects on Zimbra, which is running quite nicely at the moment?
thanks in advance for any replies.
