Uh-oh, another iPhone clock bug seems to have reared its head. Some iPhone owners in Western Australia are reporting on Twitter that their clocks have jumped forward an hour, reflecting what seems to be a bug in the daylight saving implementation.
It isn't immediately clear whether the problem stems from iOS itself (and possibly the iOS 4.3 upgrade) or from the network clock set by Optus. WA dropped daylight saving in 2009 after a three-year trial.
We know from past experience that the iPhone doesn't have a great track record when it comes to dealing with daylight saving changes. Nor does Apple have a good reputation for quickly fixing clock problems, so afflicted sufferers might not be able to trust their phones for a while -- an issue for that half of the population that shuns watches.
Update: As Gizmodo reports, it turned out to be an Optus issue and has now apparently been fixed. Thanks Vincent for the tip!
