regarding settaxis

Dear All,

I am using

cdo settaxis,2010-01-15,00:00,31days in.nc out.nc

after doing this, the date is not 15 for each month (it shows 14 or 15 or 13 depending on the months)

I need same date each months for that what I have to do??

Use 1month instead of 31days:

cdo settaxis,2010-01-15,00:00,1month in.nc out.nc

Thanks for your reply. I tried with month also but date is changing.

I need the output in "days since ....."

Please anyone suggest if knows.

I can't repoduce the chaning date with 1month.
Use settunits,days to change the units form month to days:

cdo settunits,days -settaxis,2010-01-15,00:00,1month in.nc out.nc

Thanks very much Uwe Schulzweida it works.
