DST 1 week early on 7940s

[James Guthrie]

Hi,

We're running Callmanager 8.5.1.12900-7 and I came in this morning to all our 7940s set an hour ahead.  I've checked and the callmanager server and NTP server are both correct and time zones are set correctly. 

I'm a bit confused, does anyone know if there is a patch or workaround for this?

Hi, we're in the UK and seeing a similar issue.

A quick dash around the office this morning shows 6921, 6941 and 6961 are all an hour ahead.

7911, 7962 and 8961 are showing the correct time

69xx may (and should be) running SCCP as well.

I have reported this problem here time ago, but now I can't even find my own thread.

Are you saying we shouldn't we running SIP on the 69xx, or have I mis-understood ?

We have (had) the same issue this morning.

Call Manager 8.6.2 with a mix of 7940, 7942, 7945, 8945 and 9971 handsets. All but the 7942 and 9971 handsets were showing an hour ahead of the correct time.

Our Date/Time Group was set to use (GMT) Europe/London; we changed this to (GMT) Etc/Greenwich and restarted all handsets (633 of them!) which then came back up with the correct time, i.e. GMT not BST.

Feels like there's a bug in the device software of some phone models or even in the TimeZone itself? I'm sure Cisco will release a device software patch pretty soon.

Jeff, changing the handsets to GMT would make them *not* subsequently change to BST, though.

[Jeff Clark]

Not sure about this as the previous setting was (GMT) Europe/London and has previously not had any problems changing from GMT to BST so surely changing from this to (GMT) Etc/Greenwich will not stop it working?

The only difference I can see between the two is compatbility for legacy handsets.

Hi Guys,

here is the information from Cisco Tac :

"

We are aware of this issue and have completed the testing across different CUCM versions.

The DST change dates have been updated in the latest timezone patch (2012j) that was released on 5-March 2013. To resolve the timezone problem, we need to install the latest timezone update on CUCM and perform a clusterwide reboot for the change to take effect.

The latest timezones update for CUCM is 2012j. this can be downloaded from the following link:

http://software.cisco.com/download/release.html?mdfid=283782839&flowid=26422&softwareid=282074298&release=8.6%282-2012j%29&relind=AVAILABLE&rellifecycle=&reltype=latest

For instructions regarding the installation procedure please refer to the readme file at:

http://www.cisco.com/web/software/282074298/100349/dst-862-2012j-cop-readme.pdf

We also have the alternative workaround of changing the Date/Time group to one that does not require a DST change. This will require a restart of all the phones as well to take effect. If you wish to go with this workaround, we will need to change the timezone in the Date/Time group again next weekend to reflect the correct timzeone for the IP phones.
