[v7d_transform] comp-start not working

[brancomat]

v7d_transform --input-format=BUFR --comp-stat-proc=254:2 --output-variable-list="B12101" --comp-step='1 00' --comp-start="2017-11-20 18:00" --output-format=csv  --comp-frac-valid=0 t2m.bufr tmax.csv

...creates a tmax.csv with no data. Changing the comp-start hour to "00:00" works.

(@dcesari already know the details and has the needed test data in /tmp/kalman)

This turned out to be a very difficult task when working with time_definition=1 (verification time) as is the default in observation space. It can be solved by importing the volume with --time-definition=0, which is possible since last commit, but this triggers a bug which will be solved tomorrow by merging #45.

[dcesari]

The bug has been solved after merging of #45, I keep it open because I have a partial universal solution which would allow it to work regardless of time-definition.

Meanwhile: I confirm that the --time-definition=0 thing is working with libsim 6.2.2
