Based on a real case, I try to calculate a duration through a simple substract, but I got strange results from time to time.
The begin and end hours are typed in Excel in a time format : hh:mm:ss
After import in EasyMorph, I’ve got the following issue
18:00:00 - 17:30:00 = 12:30:00 (and not 0:30:00 as expected)
empty - empty = 12:00:00 (and not 00:00:00)
