But I agree it would be nice to have a general `to_datetime` method like pandas. If we already wrote this functionality (and it was somewhat tricky), we might as well expose it to users.

Unfortunately that makes comparison with datetime objects a bit awkward.  Perhaps we should include a to_datetime() the way pandas does?  Certainly, it would be convenient to be able to do comparisons such as:

ds['time'].data > datetime.datetime(2014, 01, 01)

This is definitely not high priority though.

Otherwise we are left with dates as Python objects, which is painfully slow.

They seem under-developed / broken.
