Hi Costas,

I take it you are using 89XX phones?

CSCun11142 is a bug, affecting 89XX phones daylight settings.

Usually daylight saving is 4th Sunday of march, But this year the last Sunday is the 5th Sunday.

Regards

Matthew

Hi All,

I have a CUCM running 8.6.2, I have been informed this morning that some IP phones are 1 hr out of sync. This is happening to a few remote sites.  The NTP server is seperate and is looked after by the customer.

I have check the CUCM server and get the follwing results which look ok:

admin:utils ntp status
ntpd (pid 26786) is running...

   time correct to within 32 ms
   polling server every 1024 s

Current time in UTC is : Mon Mar 24 09:36:02 UTC 2014

Admin:

The clock on the routers sjow the same time.  Any ideas what could be the problem?

Thanks in advance for your help.

Costas
