I have the CME synchronized with a NTP server. It seems that all IP phones (7940-7960) are getting synchronized with the CME except the 7911 phones. Their time is drifted by exactly 3 hours 0 seconds from the CME.
I tried to reboot them but it didn't work.
Any idea?

Hi Walid,
Don't forget that the 7911 is a Java based phone unlike the 7940/7960's and does require this additional config. Here is a clip from the doc I sent earlier;
Confirm the configuration for Network Time Protocol (NTP) server and time zone. The following partial output defines the Pacific Standard Time (pst) time zone as 8 hours offset from UTC, specifies recurring daylight savings time (pdt), and synchronizes this router's clock with an NTP server at 10.1.2.3.
Example:
!
.
.
.
clock timezone pst -8
clock summer-time pdt recurring
ntp server 10.1.2.3
.
.
.
telephony-service
load 7941 P00308000400
.
.
.
time-zone 8 !---<==== time-zone command required for certain phone types
Step 4 For phone models other than Cisco Unified IP Phone 7902G, 7905G, 7912G, 7920, 7921, 7935, 7936, 7940, 7960, or 7985G, the time-zone command must be configured. Is the time-zone command correctly configured for your phone?
Hope this helps!
