CDO

Hi,

after upgrading cdo to .9.3 I suddenly get wrong output files:

wget ftp://ftp-anon.dwd.de/pub/data/gpcc/monitoring_v5/1982/monitoring_v5_10_1982_01.nc.gz
gunzip monitoring_v5_10_1982_01.nc.gz
ncdump -c monitoring_v5_10_1982_01.nc | tail
cdo -r copy monitoring_v5_10_1982_01.nc aap.nc
ncdump -c aap.nc | fgrep time

gives

time = 19820101 ;
}

in the original file, but

double time(time) ;
        time:standard_name = "time" ;
        time:units = "days since 1-1-1 00:00:00" ;
        time:calendar = "proleptic_gregorian" ;
        time:axis = "T" ;
...
        :time_coverage_start = "1982-01" ;
        :time_coverage_end = "1982-01" ;
        :time_coverage_resolution = "month" ;
 time = 0 ;

in the converted one, ie, time start sat 01jan0001 instead of 01jan1982.

The same bug occurs in the cdo 1.9.2 that is in fink (macOS).
I am trying to revert to the old version...
