c |
| 15 |
c o Given a time interval as a date array return the number of |
| 16 |
c seconds in that time interval. |
| 17 |
c |
| 18 |
c If one wanted to use calendar dates in this routine, then |
| 19 |
c the date should be after the calendar's refdate and timeint |
| 20 |
c would be the number of seconds that have elapsed since the |
| 21 |
c refdate. Of course this can also be done by first calling |
| 22 |
c sub cal_TimePassed and then calling this routine with the |
| 23 |
c resulting time interval array. |
