timselmean skips the first timestep
Added by ep gupal about 2 years ago
I have an hourly averaged data, and I would like to average this into 3 hourly. So, I am using the following command
cdo timselmean,3 in.nc out.nc
I expected that I would get something like
00, 03, 06, 09, ... in hours. But what I get is
01, 04, 07, 10, ...
So, in order to avoid this I used
cdo timselmean,3,0 in.nc out.nc
in order to prevent skipping the first timestep, but I keep getting the same results. How do I fix this?
Thanks.
I've uploaded the file that I am working with (with 12 timesteps).

The timestamp in the output is in the middle of the involved input time steps. Use the CDO option --timestat_date to change it to the first time step:
cdo --timestat_date first timselmean,3 infile outfile
