> Yeah if you store things as Index objects, then this would go away.

@shoyer remains unconvinced, and I defer to him without reservation - but if you think this would make sense, say so

I guess the right solution (similar to what I did for PeriodIndex in #692) would be to convert to dtype=object when necessary. Is there an easy way to get this from pandas?

Although, I do think it's pretty consistent that we use the result of `np.asarray(s)` as the values in xray. The timezone info is thrown away when you call this.
