hi guys,

need help! my iphone 5s is showing the wrong time this morning. not sure why but it almost simply just happen out of the blue. Time is set automatically to Singapore but it is showing 8:31 now instead of 9:17! have done restart, reboot and all sorts.

anyone has this problem and what can be done to correct this?

Got this problem before... When i switch on aero plane mode the timing back to normal so i go replace SIM card then no such problem since then
