Hey all, So I've got a pretty simple setup, all my phones are in the same Device Pool, with the same Date/Time Group (set to central time zone, etc.) I applied all the recommended DST patches LAST march and again in October.
However when DST rolled around this past weekend, not all of my phones updated their time correctly. I've gone through a number of phones that did and ones that didn't update. They are the same model (7961G) with the exact same Phone Load (SCCP41.8-2-1S) and I double-checked the Device Pool and date/time group to make sure they were the same. Yet half my phones show the correct time, and half do not. Ideas? I've already got a TAC call on this, but the guy is either not in the office or is just really bad about communication.
We went through the same thing last Spring :( The problem is with the phone firmware, the load you are running 8.2.1s was listed in all the DST docs as the required version, unfortunately there was a bug in this version that caused a problem with the DST Update. If you reset the Phones via ccmadmin they will pickup the correct time.
The newer DST notices now indicate 8.2.2sr1 as the minimum Firmware to be DST compliant.

I'm also having issues... except my Call Manager Server has the Right Time, Phones have the right time... yet, My "Time of Day" Script thinks the time is off by 1 hour. (Saying my office is closed) To fix, I need to manipulate the time on CCM... which in turn screws up the phones.
Can you send a link to an "Easy to Understand" document that shows ALL of the patched I need? Sorry, the Cisco site is incredibly complicated... can I just download 1 thing... and it patches everything on CCM?
This sounds like my issue. I did my updates (including DevPack) in October 2007, apparently they sent an update 4 days before the time change in November, so i am running a version behind it looks like. Thanks! i'll give this a shot, though I won't really know if it fixes my issue until November. :)
