Time calculator shows negative times incorrectly

[Bob Burger]

The advanced time calculator displays negative times incorrectly.

For example, add 55 minutes, then subtract 1 hour. It will show a total of -1:55:0 instead of -0:5:0. The Decimal field is correct, however.

Yes, that is indeed a bug.

I wonder if I should fix it so that it works well with negative time, or fix it so that negative time cannot be entered?

There is no such thing as negative time right? And I cant think of any field it would be of use.

Negative time is interesting for all calculations concerning attendance of staff.
If you want to compare the normal working time with the real working time, if this is negative, how can you show it?

Yes, I agree. It is important to show NEGATIVE time calculations, to show "time owing" for flexible hour contracted staffs.

Some staff leave early on some days, leaving a NEGATIVE time owing, so that the staff can make it up the following day, and so on.

Please show how to convert and calculate NEGATIVE time correctly?

Thanks,

Tim
