Not sure what OS version O2 went to on this phone.
I use it on weekends only and it has usually lost the time and date. Sometimes if I switch on automatic date and time it sets correctly but if left for a minute or so the clock jumps back over seven minutes. This caught me out the first time it happened (I don't even think there has been and OS updates before it started).
It keeps time if I disable automatic time as soon as it has set.
Also, someone told me that O2 don't broadcast a timesignal (I thought this was part of how the system worked).
