Hi

My setting are for East Standard/daylight savings time in the USA, you can adjust accordingly;

Find a NTP server closer to home :-) see if this makes a difference over time.

show run | include clock

clock timezone EST -5

clock summer-time EDT recurring

thanks for your reply

i tried that and it did not work

the stange thing is that the cp7940 phones have correct time

my clock settings are

clock timezone UTC 2
clock summer-time UTC recurring last Sun Mar 3:00 last Sun Oct 4:00

telephony-service
time-zone 28

i think this is related to the 7945, i installed the latest software pack  8.0.4 and still the same

Since you mentioned that the issue occurred today, it's an issue with DST.

7940 phones get the time directly from the local time on the router.  7945 get the time in UTC format from the router (which is determined by IOS applying the clock offset off the local time), and re-applying the offset again at the endpoint itself based on the config in tele-service.

* Time zone on tele-service and on the router clock look right.

* DST settings on the router look right.

So things to check:

* Make sure that 'sh clock' shows the correct local time.

* Make sure that all of your ephones have a 'type' specified under them.

* Rebuild the CNF files with 'telephony-service/no cre cnf' and then issue 'cre cnf'.  Reset the 7945s.

* Verify that the 7945s are running recent phone loads with the output of 'sh ephone ph'

If the time is still off, submit the following and I will look into it being a possible bug:

sh clock

sh run

sh ephone ph

sh ver

thanks Steve

i did all you mentioned still having incorrect clock on 7945

sh clock, sh ephone ph, sh ver : sh.txt

sh run  : shRun.txt

Elie,

It doesn't look like a bug; I can't reproduce your issue in my lab.  I can configure EET on my router and get the right time on all devices.  You've got something wrong on your side somewhere.  Open a TAC case if this post still doesn't help.

Here is the output from my lab:

pod3-3825#sh run | i clock
clock timezone EET 2

pod3-3825#more system:/its/vrf1/XMLDefault7945.cnf.xml | i one
E. Europe Standard/Daylight Time

(See attached screenshot for timezone and clock setting on phone.)

You should use the commands I used above and verify if the phone is getting the right time zone in the config, and what the current time of the phone is compared to the router.

FWIW, your DST times are incorrect.  DST happens at midnight for your timezone.  Also, you should be naming your timezone EET, since UTC is incorrect unless your timezone offset is 0.

Thanks Steven

i changed  telephony-services time-zone to East Europe  recreated cnf files and it worked
