REAL %SubTimesMono( TIME in TimeA, TIME in TimeB, )
TimeA | Absolute time. |
TimeB | Absolute time. |
The function %SubTimesMono deducts one absolute time from another one. The result will be influenced by the fact if the time offset was or was not in this interval. For example, in Slovakia, the difference between 4:00 and 1:00 a.m. can be two hours (advance to summer-time), three hours or four hours (advance to winter-time).
