Hello everyone,
On the following database I have a problem displaying durations.

The “test” column is the sum of all durations in “h:m:s” format, once the counter exceeds 24h it returns to zero, hence the false but positive 14h result here (good result 38h).
The "test2" column is the sum of all durations in "day:h:min:s" format, we still notice the same problem, the duration is negative.
I don't understand how JMP can output a negative result and then a positive result just by changing the column format.
