Cisco IP phones not getting correct time

[Jahangir Tahirov]

Hello cisco IP phone which is provisioned through CUCM gets incorrect time.

The time looks like adding 4 hours to standard time, for instance, our local time must be 18:00 PM but phones showing 18:00 + 4 hours.

Thanks for sharing, did your schenario involved CUCM version upgrade?

@George Sotiropoulos  no involved to upgrade but involved some server resource problem then CUCM pub and SUB get out of sync.

1. Our servers had resource problem and then NTP bug came.

2.IF NTP are not correct PUB and SUB got outof sync.

Solution:

1. Login to Cisco Unified Reporting web page of CUCM Publisher, went to System Reports -> Unified CM Database Status and generated new report. Then checked the report to confirm that all configuration files are fine on both CUCM nodes and both of them can communicate to the DB of each other.
2. Checked and confirmed that both nodes of CUCM cluster are authenticated by running “show network cluster” command.
3. Stopped DB replication by running “utils dbreplication stop all” command on CUCM Publisher.
4. Checked and confirmed that DB replication is stopped by running “utils dbreplication runtimestate” command.
5. Checked and confirmed that the next services are running on both CUCM nodes:

• A Cisco DB
• A Cisco DB Replicator
• Cisco Database Layer Monitor

1. Reset DB replication by running “utils dbreplication reset all” command on CUCM Publisher.
2. Monitored DB replication by running “utils dbreplication runtimestate” command every 15 min.

Hi,

I've got same issue now. Did you use PCD (Prime Collab Destroyer) to upgrade your Sub?

I had a same situation. actually your posts inspired me to try few things. this may help for interim solution

I needed EST

It was kind of Crazy.  Randomly I tried  Colombo time zone it worked perfectly.

 So i tried few + and - GMT's  nothing worked.

-1hr, +1 hr even did not work, I tried many.

I tried NY+ time zone (GMYT-5:00)America/New_York+). It worked perfectly

My system System version: 12.5.1.11900-146

8851 phone load sip88xx 12-5-1SR3-74

7811 Phone load sip78xx.12.5.1SR3-74

7965 Phone load sip45.9-4-2SR3-1S

good luck
