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 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. |

C - Introduced new routine and function names, cal_<NAME>, |
