Cisco Call Manager 7.1.3 displays incorrect time on Phones


We have a call manager cluster configured and it is configured to use time via ntp server. The time that was displayed on the phones during the initial setup of the system was correct however when since last week we have noticed that the time displayed on the phones are incorrect. The phones are displaying the UTC time instead current time for the timzezone, how do we correct this?

On CUCM 7.1.3, new timezone structure was introduced.
Because of this, the phones need to be on firmware version 9 or above to recongnize the timezone settings.
For backward compatiblity (phones has firmware lower than 9), you may choose the timezone with a star (*) on CUCM 7.1.3

Also consider updating the device pack to verify the call manager.

Then updated the phone firmware to version 9.
