A customer complained that if some users schedule a meeting in Sametime 8.0.x which should occur before noon the time of the meeting is automatically changed from AM to PM.
This can happen if you have set your Internet browser to a country/language which uses AM and PM for the time (e.g. "English (US)") and the regional settings of your server is set to a a region which does not use AM/PM but 24h time display (e.g. German).
In this case the Windows registry entries for AM and PM on the server are blank which is the reason for that problem.
To solve the issue you need to add the values for AM and PM in the Windows registry on the server.
If the Domino Server is started as a windows service (which is normally the case), then these values need to be changed in the HKEY_USERS\.DEFAULT\Control Panel\International of the registry as programs running as a service are using the .DEFAULT settings.
The values to be updated are :
Windows Registry Editor Version 5.00
After you have updated the registry and restarted your Sametime server the meetings should be scheduled correctly regardless of the language settings of the browser.
