asterisk users - Mar 2010 - time/date over POTS?

I had a customer ask me about time/date information being sent to his 
analog (attached to a Linksys SPA2102) answering machine.  I didn't know 
that POTS could carry this information.  Is this something Asterisk could 
send over SIP?

Cheers,

Time and date info on a POTS line is part of the caller ID stream. It is 
up to the analog endpoint sending the caller ID stream to know the 
current time to send. Anything that works with SIP should also have NTP 
capabilities and should be getting its time using that.
