iOS 7 seems to have trouble telling the time following the end of daylight saving time in some countries.
Several readers of AppleInsider told the blog site that the line indicating the current time is off by an hour in the Calendar app. As an example, people for whom the current time is 6:00 a.m. will see 7:00 a.m. marked instead.
The bug seems to affect only the current time display. The time is correct in the system notification bar and other locations. Alarms for calender appointments also chime in at the right time.
In the US, daylight saving time doesn't end until November 3. However, countries in Europe, the Middle East, and other regions made the switch back to standard time this past weekend.
The jump to daylight saving time has confused Apple's iOS in the past. CNET contacted Apple for confirmation and will update the story with any further details.
Correction, 10:10 a.m. PT: This story initially misstated the time switch that prompted the iOS 7 bug. Apple device users reported seeing the bug as countries switched from daylight saving time back to standard time. In the US, daylight saving time runs from March 10 to November 3 this year.
