GSM phones is being timed to transmitt in advance of time, such that their
time-slot is perfectly matched in time when it arrives to the base-station.
This doesn't prohibit the Time-Of-Day to be way off, since that is a separate
service and not all operator have it enabled in their network. So, just because
you have high timing accuracy doesn't mean you get correct time of day.

Ah well.

We thank CDMA for the wealth of Z3801A on the second hand market!
