We have discovered a problem in Clarity 12.0.4, confirmed by CA as a bug, when saving timesheets for users with a non-American locale. You get a system error and the timesheet is not saved. This is new in 12.0.4, 12.0.3 did not have the problem and it is supposedly fixed in 12.0.5. Support have told us that a hotfix is likely due to the severity of the bug. The suggested (by support) workaround is for everyone to use English American locale.
