@sinhrks I wish that could get some more uniformity w.r.t. Periods. I realize that there is a bug here with other which I fixed in tseries/base.py/.where, end up duplicating code here.

its more complicated. I needed prelim logic different fro dti & period, so would have to have a helper function. We do this a fair amount, e.g. process for timezones, run a function, then reverse. Its ok the way we do it now, but it does duplicate some code.
