A lot of older systems will set the clock from the incoming caller ID
data - the time and date are in the stream of FSK along with the number
and name. You'd want to make sure that ATA has valid time and timezones
set, then send a call into them and the PBX should jump to the correct
time and date

We had a customer that had Frontier Analog phone lines going into
their Panasonic TDA-50 PBX system. We recently ported the numbers from
Frontier to our Broadsoft, and deployed a Poly OBI508 ATA onsite. We
also replaced their router and internet connection.
Customer is complaining that their phones are displaying the wrong
time. We explained to them that we did not mess with their phone
system PBX only the input lines.
My question is, do oldschool, onsite PBX systems, like a Panasonic
TDA-50, use the analog FXS input lines from the provider (us) as a
timing source? If so, what protocol is this, and where would be change
it on the adapter?
I would think most PBX systems are like computers, and would use NTP
as the timing source.
