I installed a CUCM-BE 7.13 in place with 7941s throughout. 
My time on the phone is not correct, although in my Time/Date area on CUCM, it specifies the correct timezone and time on the server appears to be correct.NTP server sync well.

I checked date/time group configuration. device pool configuration.
, try make a new Dev Pool with a new Date/Time group and set difference timezone.

I can change the phone's date/time format, but not the timezone.
no matter what timezone I changed. the phone's time never change.

Can anyone tell me how to get the timezone correct on these phones?
Any Suggestions?

Best Regards,

Hi ,

What is the exact call manager version you have installed

Because the call manager was hitting a DST bug CSCsy25150

Upgrade the call manager to the latest patch to get this fixed

Hi Vivek Kalra:

CUCM 7.1.(3.10000)

Because the new 7941 phone register to CUCM has the TFTP "auth fail" problem.

I downgraded the Phone Firmware for CUCM 7.1(3) to 8.5(2), I will upgrade the CUCM to latest patch 7.13a after all the

phone installed.

I think my problem is not the DST bug. I have try to change the Date/Time group with many different timezone to test.

(GMT -1 ,-3 , -7 ,+3.....). The time show at the phone never change. The phone always show the time of GMT 0.

seems the timezone setting do not reach the phone.

Dude, he's not hitting that bug.  Didn't you see that he tried the timezone with "*"?  I would recommend him restart TFTP.  It looks like the phone didn't get the updated config file.

I had the exact same issue with CM 7.1.3a as well as 7.1.3b today. The 7911, 7942 and 7965 on my network would show only GMT time whereas 7925 & CIPC was fine.

After upgrading to 7.1.3b I changed to a timezone with * and it reset from Date/time group page itself and immediately the phones started working.

Sachin, are you on 7.1.3a or 7.1.3b perhaps this workaround works only with the latter??
