timedelta cannot convert to monthly data.

[effath]

Timedelta cannot convert x minute timesereies to monthly series. Each time I try to use it will upsample x minute data to 1 minute data. See

Timedelta is only for fixed offsets (seconds, days, etc), it can't and won't handle months - DateOffset and subclasses handle any relative offsets.

That said, I do see the potential for confusion given the dual use of 'M', would at minimum take doc enhancements, maybe OK with a warning for pd.Timedelta('xM')?
