I'm in San Jose. (Same Bay you are talking about?) I am on AT&T but I
have a Motoroloa Razr that's at least a couple years old.
I just checked the phone's displayed time vs the internet and also my
GPS receiver. I just eyeballed the minute turn-over but it was clearly
within about a second. Good enough for me on my phone. So, at least here
where I am, AT&T time is not off by even a couple seconds. Maybe the
issue is another iPhone problem. Do you have any friends on AT&T with
Motorola phones you can compare?

Here in the Bay Area, AT&T/iPhone time has gotten noticeably worse

Emerald Time is fine for interactive use, but what I find very impolite
is that AT&T's bad timestamps are written into the EXIF headers on photos.
Sometimes I take pictures of sundials, for example, and a 49-second
error is not negligible for a carefully made dial.
It would be amusing to arrange for a long-term record of the offset of
one's phone (which can of course change across multiple providers during
travel), say by using a background process to take a sample every few hours
against NTP sources or against GPS if the phone has it (or both).
Then any photos can be batch-corrected later if desired. Apple, give
me control over the time on my own phone, and please don't force me to
resort to these schemes :-).
Cheers,
