Why is my iPhone clock running behind 20 min? My iPhone clock is at 15:32 when the actual time is at 15:52! why is it twenty minutes behind?
The time zones are all correct and I have a screenshot that I will upload soon.
I recently had a similar problem and this solved it.

Check that your time is set automatically by going to Settings.app -> General -> Date &amp; Time -> Set Automatically to 'ON'
