[gradsusr] Forecast hour and minutes

[Jeff Duda]

Does your data file actually have data at sub-hourly intervals? If so,
change the TDEF line in the control file.  The last string gives the time
increment for each time step change.  Set it to 30MN.  If your data type is
grib, you'll have to rerun gribmap after changing the control file.
