iPhone 4 time "Set Automatically" is slow

[MoodyM]

I got my iPhone 4 new in June 2010, and it's always been set to set the time automatically.



A few days ago I noticed it's clock was now running 15 minutes slow. If I set it correctly manually, then turn Set Automatically back on, it jumps back to 15 mins slow again.



I've done a soft reset, no luck. Tried turning off/on WiFi, 3G, etc, no luck.



My iPad 2, also on Orange UK, and sitting next to my iPhone on the same WiFi networks all day at home & work, is fine, and it's also set to "Set Automatically".



What on Earth is going on?

Try resyncing you iPhone to your computer. I ran into this with my first generation iPad and that fixed it. Make sure your computer reads the correct time as well.

Restore your iPhone.

I restored my iPhone 2 weeks ago. Before that, my time when set automatically was 5 minutes late. I believed restoring the phone fixed it, but haven't checked that out yet.

So does Orange UK definitely transmit a time signal?

Update: I emailed Orange yesterday andd asked if the UK network does transmit a time signal. Orange called me back this evening and told me that time signals are not transmitted in the UK.
