IP Phones with differnet time on them

[POWERDMAN]

I have CUCM 8.6 and with 175 phones registered, MY GW's both have the correct time and timezone, so does my CUCM Publisher and Subscriber.   I have about 30% of my phones showing a different time then the rest.  They all reside on the same CUCM.  They aren't in any special groups to have different time, I have one group set up only for all the phones.  I have reset the GW time and the CUCM time in the CUCM and via CLI.  The phones won't change there current time.

Does anyone have any idea how to fix this issue?

Hi @POWERDMAN ,

I found this guide that, perhaps, could be useful for you:

Be sure that all of them are in the same device pool.

If you have different device pools, check the Roaming Sensitive Settings.

1) What is your timezone, are the phone showing the time in GMT format. I have faced a similar issue. Is the timing same on all the affected phone ?
2) On one such phone try deleting the ITL Files and reset the Phone.
3) Try upgrading the firmware to latest one.
