We have 1 user out of 100 where the Daylight Savings is not correct on their phone. Everything is patched and the other 99 phones are correct. I have tried wiping the phone and updating the software but it is still off an hour. Both the time and the appointments in the calendar are off an hour. If you go to Date/Time it is set to network and the network time shows the correct time, but the phone time above the network time is off an hour. It doesn't make sense.

We've had issues like that in the past and the first thing we have users do is check to see that they are in the correct time zone. That usually fixes the problem with our users.

Device? Device OS? DST patch installed?

From the Date / Time did you bring up the menu and Update Time?

I'll second what was said above about checking the time zone. I had a user in California whose device's timezone was set to 'Pacific Time-Tijuana'. However, Tijuana is obviously outside the US, so they don't acknowledge the DST change that congress instituted. When he changed it to 'Pacific Time-California' everything was cool.

Yes the BES server is updated and the Exchange servers are updated according to the DST upgrade instructions. The device's OS is updated to 4.2 and I also installed the DST patch on it although not neeed. I tried wiping the device and re-adding the user. I checked the TimeZone and it is correct and I tried hitting the update time. Wiping the device and re-activating the user fixed the time on her phone, but her appointments still show up an hour off on the Blackberry.

Run the DST Repair Tool on the BES database to query if they have incorrect backup data. If they do, run the repair tool and tell them to check back with you tomorrow. It's very simple.

Command-Line - Query:
Single user: RepairTimeZones.exe -u -db BESMgmt -n DBSERVER
All users (in config db): RepairTimeZones.exe -b all -db BESMgmt -n DBSERVER

Command-Line - Repair:
Single user: RepairTimeZones.exe -u -repair -db BESMgmt -n DBSERVER
All users (in config db): RepairTimeZones.exe -b all -repair -db BESMgmt -n DBSERVER

Default action is to query only (no changes/updates). Database name (-db flag) could vary, depending on your configuration. DBSERVER name (-n flag) could be a remote SQL server name or BES server name (local MSDE instance).
