CME time issue

Answered Question
Apr 2nd, 2008
User Badges:

We are running CME 4.0(3) on a 2821 series router. Router is in sync with NTP routers & the router is displaying correct time ( after the DST change). But phones are still showing old times, one hour behind correct DST time.

Before DST was applied on 30th March in Europe timings on all phones were correct.

Resetting phones doesn't help. Any other solution? I am not sure that a reboot of the router of resetting the CME module will help.

Hi, according to official sources, the correct designation for daylight saving in Europe is CEST. It is called so to avoid confusion with the American timezones.

Then again whatever abbreviation you use won't make a difference.


Thanks for the nice rating and good luck!

Do you have a command like

clock summer-time CEST recurring last Sun Mar 2:00 last Sun Oct 2:00


in config ?

Paolo,

Thanks for the reply. No, we don't have this command on the router.

One more thing - the router is in Eastern Europe, CET timezone. DST is applicable from 30th March. Anything extra I need to do on account of this?

Abhijit Das.

Hi, DST has "moving dates" each year. The command I suggested above is applicable in Europe for the foreseeable future.

Paolo,

One more input - NTP is synced with NTP router. One interesting thing, sh clock shows router is behind by one hour, while CME (web-admin page) System Parameters -> System time shows the correct time.

On CCME confirm below mentioned command:


For India:

On Router:

clock timezone IST 5 30

clock calendar-valid

network-clock-participate wic 1


On Telephony service:

time-zone 39

create cnf-files version-stamp 7960 Mar 19 2008 10:21:13


If you make the NTP server on router itself,this may solve your problem


If CUE is Alos there,try below mentioned command,and reboot the phones.

ntp server 10.194.56.10 prefer


10.194.56.10---Router IP

Hi Abhijit,


Hope all is well my friend :) You may also have a phone firmware issue. Check this out if you are using "Java Based" IP Phone models. These would be the minimum recommended firmware versions;


CME - DST changes are outlined in this doc;


Field Notice: FN - 62686 - U.S. Daylight Saving Time (DST) Policy Changes Effective March 2007 - Cisco CallManager Express (CCME)

Customers who are using the following Cisco Unified IP phone models:


7906


7911


7931


7941


7961


7970


7971-GE


are required to upgrade to the following phone firmware to display the correct time:


* CCME 3.X, 4.0 and 4.0(x) customers need to upgrade the phone load to 8.0(4)SR2.


* CCME 4.1 and 7931 customers need to upgrade the phone load to 8.2(2)SR2.





The new Firmware will need to be copied onto Flash) Here's how;

Rob,

Hope all's well with you dear friend!! :-)

I have gone through a post of yours ( DST time , 28th March) where I found the new US DST policies).

I strongly feel that "clock summer-time EDT recurring 2 Sun Mar 2:00 1 Sun Nov 2:00" will fix this issue.

A few points though :

The router is in Eastern Europe, timezone CET, so instead of EDT, we put CET or CDT ( not sure about CDT).

"sh clock" shows incorrect time, but CME web-interface ( System Parameters) shows correct time.

We are using 7911, 7912's & 7940's. I don't think these are Java phones. Further, we have the latest load for 7911, 8.0(4)SR2. ( this load fixed a time issue faced by 7911's & the solution was yours :-) )

Time-zone is already set, "clock timezone CET 1" present on the router.

Kindly let me know if anything else is required.


Regards,

Abhijit.

Hi Abhijit,


Life is good, we are getting a new ES soon to fix the upgrade problem we had on the weekend :) I think CME Master Paolo has certainly given you the correct info that I feel confident will fix the issue.


For your question;


"we put CET or CDT ( not sure about CDT)."


I think CET will work!

Rob,

Thanks again. Alas I am not doing that good. Lot of cost-cutting going on in my firm & my salary is being cut every month (-:

It's the love for IP Telephony which keeps me going.

Pray that your issues are fixed with the new ES.


Take care dear friend,

Abhijit.
