CCM 4.1(3)SR1 w/ DST patch & firmware 8.2.1, I had to reset my 7970's for them to pick up the new time.

Did reset the phone and the time is still wrong. FYI......the ccm time is changed correctly as well as other phones.

In CCMXXX database table "TypeTimeZone" and manually set the "stddate"

and "dstdate" to "0/11/0/1,2:0:0:0" and "0/3/0/2,2:0:0:0" respectively for each US timezone.

After that reset all 7970s...

OK, some update.

We checked the SQL database and the setting is right.

So we ran out of idea and we did another reset of the all 7970 phones and they came back with right time now.....


There's gotta be a problem with the 7970 load. We were experiencing this too. We rebooted the phone (i.e. unplugged and replugged it in), same problem.

However, our vendor called me and said that we'd have to perform a reset in CCM. We did it, and it worked. However, it should not be this way. This basically means that it's a manual process. It should've adjusted by itself like all the other phones. There has to be some sort of bug in this for the 7970s.

I have a call into TAC. Will post the outcome when I have it.

Has anyone noticed a problem with IP Communicator? Our IP Communicator phones are not picking up the correct time (prior to version 2.0.2) If you are running IPC 2.0.2 you are fine. Any older versions and you are off by one hour.
