mergetime fails to skip duplicate timestamps
Added by David Wang about 10 years ago
I found mergetime failed to skip duplicate timestamps when using piping. For example,
cdo mergetime a.nc b.nc c.nc out.nc # correctly skip duplicate timestamps cdo select,year=1950/1999 -mergetime a.nc b.nc c.nc out.nc # fail to skip
SKIP_SAME_TIME is set to 1. I'm using CDO version 1.6.1 on a linux box.

Hi David,
You can't combine mergetime with other operators when using more than one input file.
The following command
cdo select,year=1950/1999 -mergetime a.nc b.nc c.nc out.ncwill result in
cdo mergetime a.nc x.nc cdo select,year=1950/1999 x.nc b.nc c.nc out.nc
Here is an example using the wildcard '?', this will work as excepted
cdo select,year=1950/1999 -mergetime '?.nc' out.nc
The explanation can be found in https://code.zmaw.de/projects/cdo/embedded/1.6.3/cdo.html#x1-90001.2.3
Best regards,
Uwe
