We are running CCME 4.0(0). We have 7961, 7941, and 7911 phones. The time displayed on the phones are all wrong. When I log in to the web page of the phones the time zone parameter is blank. In Telephony Service I have the parameter "time-zone 5" set for Pacific. I have this same CCME configuration with same hardware and CCME version at several other locations. The times are correct on those phones and when I log onto the webpage of any of those phones it shows the time-zone parameter as Pacific Standard/Daylight Time. I have reset the phones several times. How can I force the phones to recognize the timezone?
