[CF-metadata] Is there a convention defining day offsets to use for monthly average time series?

Hi.

I have a time series of monthly averaged values. I have an
integer-valued time coordinate variable and an associated time_bounds
variable. Is it correct to use the 15th of February and the 16th of all
the other months for my time centers, or should I use the 16th of every
month?

Also, should I do anything differently if my data are climatological
monthly averages (say, over 30 years of data)? And, in this case,
should the time coordinate values be day numbers from the beginning of
the 30-year time interval, the end of the time interval, or something
else entirely?

Grace and peace,

Jim Biard
