To enable an evolutionary approach DateTime <-> datetime conversions
must be made round-tripable. This is currently difficult as DateTimes
have a resolution of milliseconds and datetimes a resolution of
microseconds. I propose:
* Increase the resolution of DateTimes to microseconds
* Modify the DateTime constructor to handle datetime objects
* add an asdatetime method which will return a datetime object
(avoiding any issues with floating point conversions).
If there is support for this I will supply a patch.
