[gradsusr] GFS (timetables data)

[Thomas Robinson]

May,

You have only 1 time in your file, so the time increment shouldn't matter.
Grads has to have a time increment, even if there is only one time in the
file.  If your averaging method worked correctly, you probably don't need
to worry about it.
