Currently time setting on the IP Communicator is not

synchronized with CCM. IP Communicator displays GMT only.

IP phones display correct time (GMT-4).

IP Communicator is in same Device Pool(CMLocal) as Cisco IP phones.

CCM 4.13

IP Communicator 2.12

Does anyboy has any suggestion?

Your reply is highly appreciated.

USER INTERFACE: does not display time using CallManager time zone



The time on the IP Communicator phone is incorrect. The time displayed is GMT

instead of local time zone.



If the CM Date/Time group uses 'local time zone of CallManger' instead of

explicit time zone setting, the IP Communicator will display the time in GMT.



Explictily set the time zone setting to the local time zone

Hi Hin,

This bug CSCec78626 seems to happen on older IP communicator version(1.x)

I already create a new device pool for soft phones only, and set the time zhone to local time zone(GMT-4).

The soft phones still display GMT time, not local time(GMT-4).

Any more suggestion?

If your post is helpful,i will rate it.

Hi All,

I know that this question is quite old.  However, I think that it isstill relevant today.  I have a CIPC version 2.1.0 and have run it againstversion 7.1 and version 8.0 of CUCM and got the same results:  clockshowing GMT.

I have a specific issue with central time (GMT -6).  I had configured GMT -6 Americas/Winnipeg and ran into the clock issue.

I tried GMT -6 Americas/Regina and my CIPC would not even register...wouldget past "Updating Locale".

The one that worked for me was GMT -6 Americas/Chicago...this one is compatible with older phone loads and did the trick for me.

Seems a bit flaky so try different setting for your Date/Time group and hopefully you will eventually get the right one.

Ran into the same issue, had to switch to one of the time zones with the +- at the end so that it worked for older version loads (as listed under DateTime). Once I changed to one of those, I was fine, but when I used one like Toronto that doesn't have the indicator, it didn't work for my IP Comm.
