I have upgraded out system from 7.0.3 to 8.0.2hp2 and have an issue with the GroupWise Client Monthly Calendar display.

All appointments in the Monthly view are display in 12 hour format rather than 24 hour format.

Under Tools | Options | Calendar | Date/Time the System Format is set as follows:

Time: 13:46:50
Short date: 03/08/2011
Long Date: 03 August 2011

General GroupWise format
Time: 13:46:50
Date: Short Date 03/08/2011

Specific GroupWise formats
Main Window: Short Date, Time 03/08/2011 13:46:50
Properties: Short Date, Time 03/08/2011 13:46:50
File info: Short Date, Time 03/08/2011 13:46:50

Which is all correct

Windows Regional Settings = English (United Kingdom)
Time = HH:mm:ss

I have tried setting time to hh:mm:ss and back but makes no difference.

Have tried on Windows XP SP3 and Windows 7 SP1

Time is displayed in mails correctly and in other calendar views like weekly and daily.

Using a GroupWise 7.0.3 client the times are shown in correct 24 hour format, although we have a date issue where some dates are shown Americanised ie mm/dd/yy and others in UK format ie dd/m/yy.

Thanks in advance.
