Duration |
Duration is measured inclusively from the start of the activity (as given in the START variable). In the output, any activity that lasts part of a day is displayed as lasting a full day.
The INTERVAL= option in a PROC CALENDAR statement automatically sets the unit of the duration variable, depending on its own value as follows:
INTERVAL= | Default Length of the Duration Unit |
---|---|
DAY (the default) | 24 hours |
WORKDAY | 8 hours |
You can override the default length of a duration unit by using
the DAYLENGTH= option
a D_LENGTH variable in the CALEDATA= data set.
