Schedule Maintenance Mode tool might not work correctly with non-english local settings

If you want to use the Schedule Maintenance Mode tool from OpsMgr R2 Admin reskit (Download) you might run in trouble in case your system is running with non-english local settings.

This happens if your configured locale doesn't use AM/PM time symbols. In this case you can't schedule any Maintenance Mode in the afternoon/evening. :-(

 

The reason is that the Schedule Maintenance Mode tool uses 12 hours instead of 24 hours with this local settings.

This is a known issue blogs.technet.com/b/momteam/archive/2011/06/21/schedule-maintenance-mode-reskit-tool-info.aspx

As a small workaround you can change your local settings on the system you run the ScheduleMaintenanceMode.exe by setting the AM/PM Symbol on your local settings option.

 

Once you set this, start the Schedule Maintenance Mode tool again. Now you are able to set schedules in the evening too. ;-)

Have fun ;-)
