Just in case this benefits anyone in another year... 

It turns out that there was a problem with the 2009i timezone (show timezone config). In Europe, DST generally applies on the last sunday of October, but the logic within 2009i is for the fourth sunday. It turns out that this October (2011), the last sunday is the fifth sunday! 

Regards 

James.

Hi James 

thanks for your feedback. 
We tried differnt Date/Time Group configurations and found out that Africa/Windhoek* works. 
So we change the Date/Time Setting this night to this Timezone and change it back next sunday. 

I hope nothing else is affected, if we change the Date/Time configuration to Windhoek. 


Regards 
Reto

Reto, 

On a not dissimilar version, we noticed the Europe/Amsterdam and Europe/Paris times fell back one hour this weekend as well. It appears to have affected Time of Day routing, but not actual IPPhone clocks. Incidentally, if you check the Date/Time Group configuration of your 7960 phones, are you running a timezone with a ++ symbol beside? 

For our particular problem, I moved the partition to a different timezone and have raised a TAC case. 

Regards

hello group 

we run a CUCM 7.1(3a) and this morning all of our 7960IP Phones allready changed the time back from DST to normal time. Not so the 7961 IP Phones. 
The phones have SW P00308010100 and Boot SW PC0303010001. 

Is anyone else having the same problem or how do I fix this quickly? 

Thanks Reto
