He claims ever since he switched providers, that his phone system date/time stamp has been off (says November, 4am). His phone system guy called me and asked if I was "sending" time over the analog lines. I am unfamiliar with analog phone lines sending a date/time stamp, but I am sort of new to this game. Is this possible?

It is sent as part of the caller-ID data stream when a call comes in.

They said they are able to configure the phone system to proper time, but then when calls come in, the date/time changes back .

I just checked the clock on the Adtran and indeed it says:

Adtran#show clock 04:26:42 UTC Sat Nov 28 2009

Adtran 908e supports SNTP, just configure an SNTP server and set the timezone on the box. This will also keep your logs and monitoring accurate. You can use us.pool.ntp.org if you don't have an on-net time server. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
