That's kinda where I'm at too. I'm sure our ATA's were giving time to
people's handsets too because this came up a lot after they changed the
daylight savings dates. ATA's that didn't have that fixed would give
people wrong times for a few weeks near the DST changes.
Exactly how they do it is where I'm fuzzy. I think you're right that
they can bury some modulated data in the ringing.

With my Non-phone background, I think that it sends the time as part
of the CID string. So a customer may manually set the time on a
phone, and then when the first call comes in, it resets the time. I
usually track time issues down to an incorrect time setting in the ATA.

I think they do send the time on POTS lines. ADSI maybe?
Are the time and timezone both correct on the ONT?

We recently have moved a couple customers off of Frontier to
dialtone derived from our ONTs that are having problems. The only
problem is that the time displayed on their phone is now no longer
correct. They set the time and it stays for a bit, but then resets
to something not correct. I guess when they were on Frontier, it
worked correctly all of the time.
Would Frontier have had some kind of service setup on their POTS
lines that provided time? I've never heard of such a thing.
I would think it was just a failing phone system, but to have
multiple customers converted in a month all have the same problem?
Seems fishy.
I'm assuming it's some kind of key system, but I don't know what as
I haven't seen it.
