We remove the NTP server from the Call Manager 6.5 and configure manual TIME setup on the CUCM but the IP Phone showing 7 minutes difference.
We reset and restart the Phones not no effect. What other thing we can do to accomplish this issue.
Can u share the output of command utils ntp status from CLI?
Secondly, how did u remove ntp from CUCM?
I remove the NTP Server IP Address information from the OS Administration NTP configuration.
Output for the Command
admin:utils ntp status
ntpd (pid 32278) is running...

I was just goig through troubleshooting DOC .the problem which u are facing is may be because of BIOS which has wrong time and phones are picking that time after NTP has been removed.
Can u cross-check BIOS settings during maintenance hours ?
We did'nt cross check at the time we remove.
So we need to restart the Publisher so the Local Time setting will be update on the Server BIOS?
