[time-nuts] NITZ Timestamps

2013-08-21 Thread Tom Harris
Here's a general question about the NITZ timestamp that is sent by the
phone tower when your mobile connects to it. Why are they so far off from
the actual time? I have seen offsets up to 15 seconds behind, mind you this
was from a tower in the bush, city towers are usually only 2 secs behind.

Maybe the 15 second offset was to compensate for the old Android bug that
derived time from GPS rather than UTC ; Sprint told me at that time they
drove most towers with Stratum 2 ref. and only my Android phones exhibited
the issue. The other ones were no more than 0.1 sec off.
