All my 7920's read the UTC time and don't take the timezone into account. For example, time on CCME is 13:00:00 UTC. I have a "timezone 12" command in telephony-service. All other phones will display a time of 8:00a but the 7920's display 13:00. Any ideas on how to fix this. 7920's have latest firmware (3.1).
Fixed my own problem. Added a "clock timezone EST -5" command on the router.
