Asterisk does not push time to the phones. The phones themselves will 
contact an NTP server to obtain the correct time.

Best practice is to configure ntpd as both a server and client on your 
Asterisk server and point your phones to it. That way your phones will 
have exactly the same time as your Asterisk server.
