# Problem with time calculations in Calc - LibreOffice 4.0 [closed]

In previous versions of LibreOffice, for instance: 03:00:00 (3 hours, zero minutes, zero seconds) minus 04:00:00 would give -01:00:00. Now in LibreOffice 4.0, the calculation is done "modulo 24 hours", and the result is 23:00:00. Is it something dependent on a particular setting which changed its default, or is it a bug?
