Good Afternoon CSC,
We are facing an issue on our Ireland VG where the time on the phone is 1 hour behind the time shown on the router. I have changed the time-zone to make it one hour ahead but still the phone shows the incorrect time.
NTP is configured and synchronized: -
Clock is synchronized, stratum 8, reference is 127.127.1.1
I have done a "create cnf" and then carried out a reset to the phone but its still reflecting incorrect time.
CME version 2800 Software (C2800NM-IPVOICEK9-M), Version 12.4(22)T5
Firmware on the phones: - phone/7945-7965/apps45.8-3-2-27.sbn
We are using only 7965 and 7945.
Please advise how we can fix this issue.
Many Thanks,
Sam Xavier.

You may need to update phone firmware.
Also note you are not using NTP, but just internal clock, that equals to not configuring NTP at all.

Hi Sam Xavier
As kaja_2kj3 mentioned set teh timezone under telephony services and create configuration files under Cme.
after that reset all phones it will work.
router updates own clock from NTP server but Ip phones take time and date updates from CME not router.
Check below link:

Hi to all,
I have read all your helpful notes. I need your help on the this problem.
The CME has the below configuration:
///
clock timezone EET 2
clock summer-time EEST recurring last Sun Mar 3:00 last Sun Oct 4:00
network-clock-participate wic 0
network-clock-participate wic 1
network-clock-participate wic 2
///
///
telephony-service
time-zone 29
time-format 24
date-format dd-mm-yy
///
All the IP-Phones 6941 has the correct time but unfortunately all the 79xx IP-Phones have wrong time (missing one hour).
Could you please help me on this?
tnx a lot

Please dont forget phone "type" under ephone-dn, it looks like:
ephone-dn xxx
number xxx
type 79xx
Then reset the phone, you also can check by "show telephony tftp-binding " and looking for item of your phone "SEPxxxx.xml" , it contains the timezone setting for IP Phone
