I have an excel spreadsheet which I changed the date system to 1904 to be able to display negative hours. The problem is that it often happens that -00: 00 values appear when I subtract timings.
What I have analyzed is because the date is 01/01/1904, but in the field I do not want to display the date, I only care about the schedules.
I've tried using SE function to identify if it is less than / equal to zero and does not resolve. Anyone have any suggestions?
