The DateTime class internally stores the value as seconds since the
epoch. It uses a RealType of RealType.Time.

Is time the domain or range of the FlatField? (I would assume domain,
since your data is a function of time) If it is the domain, use
a Gridded1DDoubleSet instead of a Gridded1DSet for your domain of
times. You can use the static methods makeTimeSet to get you
a Gridded1DDoubleSet from an array of DateTimes or doubles.

For range values, only floats are supported.
