I have configured system --> Date/Time Group with "Eastern Standard / Daylight Time. I have partitions configured with the same time zone. But this failed to work during recent time change for Daylight time.(3 days ago). Is this a bug or I am missing something?
The CM itself is synced with an NTP and has successfully adjusted for correct time, but my partitions which have TOD routing failed to work.
The phones display wrong time because of this bug CSCsy25150 : 7960 and other phones incorrect time after DST on March 08,2009
Certain models of Cisco IP Phones fail to get the time information from the Cisco Unified Communications Manager server component.
Cisco IP Phone Models: 7905, 7910, 7912, 7920, 7921, 7925, 7935, 7936,7937, 7940, 7960
Time of Day routing will also be an hour behind.
Any first generation IP Phone registered to Cisco Unified Communication Manager 5.1.X and above where Daylight Savings Time changes are in affect.
Cisco Unified Communication Manager 5.1.X and above where Time of Day routing is being used
1. Using CUCM Admin go to: System---Date / Time Group
2. Create new Date / Time group with one hour extra of local time.
3. Go to System --- Device pool
4. Create a New Device pool and assign the (one hour extra Date time
group) to this device pool.
5. Assign the new Device pool to and Cisco IP Phones that are displaying
the incorrect time.
NOTE: This workaround action will need to be reversed on 03/15/2009 as the
CUCM time update will occur. Please plan to change your Device pools back
the original Date / Time group accordingly.
