NetCDF with GrADS

  I used the ccm2nc program to convert a CCM history tape to NetCDF
format (DJFdata.nc). When I attempted to read it into GrADS 1.7 (using
the sdfopen command), the following error message was printed:

Scanning self-describing file: DJFdata.nc
Found 72 data variables in SDF file.
Time unit has too small an increment for use with GrADS (min. 1 minute)

Presumably the unit is seconds. Has anyone run into this problem before?
It seems like either the ccm2nc program should have some kind of relevant
option, or GrADS, but I don't know which. Any help would be appreciated.
