D_TIME_UNIT in a multi netCDF descriptor file

[BROCKMANN_Patrick <patrick@xxxxxxxxxxxxxxxxxxxxxxx>]

Dear ferreters,

Thank you for the trick to get the last timestep of
a climatological axes (shade/L=12 clim[L=11:12]).

But I still have a problem using this time climatological axes 
and my own Multi netCDF.

The problem comes from the unrecognition of my time axis which
is not read as monthly.
To correct this, I'd like to know what is the exact value of 
the namelist entity called D_TIME_UNIT in the descriptor file if 
I want to represent months.

I have already tried 2592000s (for a month of 30 days),
2629746s (for a month of 730.485 hours), 2635200 (for a month of 30.5
days)
but none of them are recognized when I open my multi netCDF 
and I look to the time axis.

--> Nothing is written in the parenthesis after TIME_STEP
