Abstract
Add and subtract times and intervals.
1 Instruments/Modes
Instrument Mode
n/a n/a
2 Use
pipeline processing no
interactive analysis yes
3 Description
timecalc will calculate the number of seconds between two time intervals, or add a number of seconds
to a given time.
4 Parameters
This section documents the parameters recognized by this task (if any).
Parameter Mand Type Default Constraints
t0 yes string
Starting time, e.g. 1998-11-25T17:21:00.
arg no string dt dt|t1
determines the second argument. If 'dt', the time 'dt' will be added to t0 and the result is printed. If
't1', the dierence between t0 and t1 is printed.

dt no real
time interval, possibly negative, in seconds.
t1 no string
end time, e.g. 2000-01-01T00:00:00
5 Errors
This section documents warnings and errors generated by this task (if any). Note that warnings and
errors can also be generated in the SAS infrastructure libraries, in which case they would not be docu-
mented here. Refer to the index of all errors and warnings available in the HTML version of the SAS
documentation.
