Time is not controlled by UCM. The router should be synchronized to the same NTP source as the UCM cluster.

Cisco IOS Network Management Configuration  Guide, Release 12.4T - Configuring NTP


ntp source Loopback0
ntp master
ntp update-calendar
ntp server source Loopback0

Also be sure to set the appropriate time zone and DST rules if applicable to your location.


clock timezone CST -6
clock summer-time CDT recurring

Lastly, the telephony-service or call-manager-fallback also has a time zone command that should be declared for the phones:


time-zone 8
