For the /reading style SolarQuery API queries, unexpected results can be returned on datum streams that hold records of "incomplete" datum around the given start/end dates. By "incomplete" I mean that an accumulating property is only present sometimes, but it is desirable to get an actual reading based on the datum where that property is present.

For example, given a datum stream like:

And a Difference query date range of 00:00 - 00:15, the current result would have the reading date range of 00:00 - 00:15 but would not have a result value for Meter, because the 00:15 datum does not have a Meter value. The desired result would have a reading date range equal to 00:00 - 00:10 and a Meter result value of 2 (102 - 100).
