All SCCP phones clocks gone back 1 week early, CUCM v11.5

[carl_townshend]

Hi All

All my SCCP phones clocks seem to have changed time to 1 hour back 1 week early.

The SIP phones all seem to be OK.

We are running CUCM v11.5

How should I resolve this ?

I cannot afford to wait a week without changing it to the correct time

Many thanks

Check there the NTP Server source from, check NTP Settings sync status.

If CUCM is NTP Soruce post from CUCM

#utils ntp status

Hi

We are not using NTP

[balaji.bandi]

how is your CUCM/ Phone clock source from ?

[carl_townshend]

It was manually set.

I tried creating a device pool and date/time group with NTP, it did not fix the issue.

I have logged a case with our third party, they said a DST fix is needed.

Have you checked if the ntp is correct on your CUCM?

utils ntp status
