I noticed that my clock was set at the wrong time on my iPad, 4th generation wifi only, after jailbreaking this afternoon. The minutes were correct, but the hours were seemingly on GMT. I checked in Settings -> General -> Date & Time and it was set for automatic. The spinner kept going like it couldn't figure out where it was. I checked maps and my current location is correct, so GPS is working.
To get it set correctly I went for manually and chose the correct time zone, then set the hours. I didn't have this problem on my iPhone.
I installed I've only installed iconoclasm, infinidock and sbsettings. I don't think any of those would have monkeyed with the time.
Any hints as how to get the time to be automatically set again? Perhaps the time servers are being hit extra hard right now?
Edit: and iFile.
