[gradsusr] gadsdf: Time unit has too small an increment (min. 1 minute).

Hi

My GrADS version/configurations are "Config: v2.0.a8 little-endian readline printim grib2 netcdf hdf4-sds hdf5 opendap-grids,stn geotiff shapefile "

I have monthly mean files from NCEP Reanalysis;

I used "cdo -r  yseasavg air2m.mon.mean.nc air2m.seas.mean.nc" to generate seasonal climatologies but I get the following error;

sdfopen air2m.seas.mean.nc 
Scanning self-describing file:  air2m.seas.mean.nc
gadsdf: Time unit has too small an increment (min. 1 minute).

I also tried;

cdo yseasavg air2m.mon.mean.nc air2m.seas.mean.nc

But when I;

ga-> sdfopen air2m.seas.mean.nc 
Scanning self-describing file:  air2m.seas.mean.nc
SDF file has no discernable time coordinate -- using default values.
gadsdf: SDF file does not have any non-coordinate variables.


Any suggestions on how to handle this?

Thank you.
