Sometimes Excel reports will display strange results (ie: several thousand working hours/day). This is not a Time2L bug. Unfortunately, this is a peculiarity of Microsoft Office and Microsoft Windows. There are 2 different versions: one seperates decimals with commas (ie: in the German version) and one with points (ie: English and others).
There is a built-in solution in Time2L on how to fix this problem without having to change your entire system right away. Simply make the appropriate selection in the drop-down box just before exporting the values. If you have German Excel or Windows, then you will likely need to choose "Semicolon"at this point.
