[SOLVED] Zimbra Mobile web client shows appointments four hours early

[ThorGoLucky]

Hi, a user has appointments that are scheduled correctly when viewed with the Ajax web client, but the appointments are showing as four hours earlier when viewed with the Mobile web client. I did not find this problem in Bugzilla. Before I report it, is anybody else noticing this problem? Thanks.

Zimbra 5.0.2 NE 64-bit
Red Hat EL 4 server
Windows XP Professional client
US Pacific timezone

Meeting detail view times may also be wrong in the Standard HTML client and in the HTML REST view, mail.example.com/home/user/Calendar.html

I'd be surprised if I was the first to report this, but I couldn't find anything similar:

Bug 25229 - Appointment detail view in HTML client (only) uses wrong time zone

Meetings created in ZWC display are fine. Times are displayed wrong if created in a different time zone or with Outlook.

We saw something similar to this and it turned out to be the way time zones were being applied for the class of service that user was in. Try explicitly setting that CoS or user's timezone (Preferences, Calendar section) and see if things get better for you.

I think the real issue here is with 5.0.x the timezone settings are paid attention to in a different manner than they were in previous releases. Check out the Client Behavior section in this wiki page for more details. That's what clued me into this change.

Yeah, if CoS or user time zone is wrong, then all events will be off in all HTML/mobile views.

But even with the viewing user's time zone correct, there's still a bug displaying individual events created by ZCO, which puts the local time zone in the DESCRIPTION but uses UTC time for DTSTART/DTEND. http://bugzilla.zimbra.com/attachment.cgi?id=9062 shows the "Fax Server Group" meeting time correct in the day view on the left, but the meeting detail view on the right has an incorrect Date: header.

Ah, that's a new bug I hadn't seen before. We'll be on the lookout for it.

Excellent bug report, btw.

Ah ha, I found the problem with this specific user. His zimbraPrefTimeZoneID was incorrectly set to GMT-12 instead of GMT-8. That would account for the 4-hour difference. Thanks.

zmprov getaccount user@domain

To update all accounts:

for a in $( zmprov getAllAccounts domain ); do zmprov modifyAccount $a zimbraPrefTimeZoneId "(GMT-08.00) Pacific Time (US & Canada)"; done
