Time on IP phones changes from standard to military time

Core Issue

After Cisco CallManager is upgraded to version 3.2(3), the time displayed on IP phones changes from standard (12 hour clock) to military time (24 hour clock) and back again.

However, when IP phones are set to military time, the phones display correctly in military format. The IP phones remain in correct format until they are changed to standard time.

When the phones are set to standard time, they begin to change from standard time to military time again.

Resolution

This occurs because Daylight Savings Time is not taken into account. It is addressed in Cisco bug ID CSCdz49110 - Phone displays wrong time in some time zones.

The issue is fixed in Service Pack 2 ciscocm-ffu.3-2-3-sr2.exe and later versions. To download the patch and the readme files from Cisco.com, refer to Cisco CallManager Version 3.2 Software Download.
