I have a Cisco Call Manager Express version 12.4. The time is correct on the switch but 4 hours back on the phones. No matter what change I make to the time zones or anything affects the phones. Does anyone have any advice???
 
You might want to ask this question in the CallManager forum, too.
 
What type of phones are you using?

I was told by Cisco that the older phones (7940's & 7960"s) pull their time settings directly from teh router running the CME.

The newer phones derive their time zone settings individually, and can be set from teh following:

router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#telephony-service
router(config-telephony)#time-zone ?
<1-53> select timezone name used by IP phones (offset in minutes)
1 Dateline Standard Time -720
2 Samoa Standard Time -660
3 Hawaiian Standard Time -600
4 Alaskan Standard/Daylight Time -540
5 Pacific Standard/Daylight Time -480
6 Mountain Standard/Daylight Time -420
7 US Mountain Standard Time -420
8 Central Standard/Daylight Time -360
9 Mexico Standard/Daylight Time -360
10 Canada Central Standard Time -360
11 SA Pacific Standard Time -300
12 Eastern Standard/Daylight Time -300
13 US Eastern Standard Time -300
14 Atlantic Standard/Daylight Time -240
15 SA Western Standard Time -240
16 Newfoundland Standard/Daylight Time -210
17 South America Standard/Daylight Time -180
18 SA Eastern Standard Time -180
19 Mid-Atlantic Standard/Daylight Time -120 20 Azores Standard/Daylight Time -60
21 GMT Standard/Daylight Time +0
 
I tried the time zone setting, and that did not work. The issue is that the system time and the phone time are 4 hours off. The phones look like they are registered local. How do you confirm that?

Where is the Call Manager forum? Is it on the Cisco site?
 
I assume the time on the CME router is sync'd off a real time source and the time-zone is set correctly?

Yes---post a config of the CME router...
A free source is 64.113.32.5
