We are running CME 4.0(3). The 7911 series IP phones are showing incorrect times. Alll other phone models ( 7940) work fine. We tried the time zone command. Upgraded the IOS to 12.4(4)XC7. Nothing helped. Current phone load is SCCP11.7-2-1-0S. This is driving me crazy..
These Firmware Loads are also available for your CME Version. It is a little hard to find sometimes (about a third of the way down the page) :)
