CDO

Hi all,

I am trying to convert some netcdf to grib but setcalendar does not work as expected.
My original data have a 365_day calendar, so I use the following command for the conversion:

cdo -f grb setltype,1 -chparam,-1,1 -setreftime,1980-01-01,00:00:00,hour -settaxis,1980-01-01,00:00:00,6hour -setcalendar,365_day ps.nc ps.grb

However, looking at the output the grib file I found a proleptic_gregorian calendar:

File format : GRIB
    -1 : Institut Source   T Steptype Levels Num    Points Num Dtype : Parameter ID
     1 : NCAR     unknown  v instant       1   1     55296   1  P16  : 1             
   Grid coordinates :
     1 : lonlat                   : points=55296 (288x192)
                              lon : 0 to 358.75 by 1.25 degrees_east  circular
                              lat : -90 to 90 by 0.9424084 degrees_north
   Vertical coordinates :
     1 : surface                  : levels=1
   Time coordinate :  unlimited steps
     RefTime =  1980-01-01 00:00:00  Units = days  Calendar = proleptic_gregorian
  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss
  1980-01-01 00:00:00  1980-01-01 06:00:00  1980-01-01 12:00:00  1980-01-01 18:00:00
  1980-01-02 00:00:00

Any idea on what is going wrong?
Thanks into advance for help.
