The daylight saving bug strikes again on some Apple iPhones.
It happened on devices running the latest version of Apple's mobile operating system.
Some users saw two different times displayed on their calendar app.
Apparently, it was caused by a change that moved daylight saving time back a week in 2007.
The bug reportedly does not affect scheduled alarms or calendar events unlike a bug in 2010.
That one did not properly shift alarm schedules when daylight saving time ended, causing some European iPhone owners to wake up late for work, while Australians were woken up early.
