Error if setting a time_range for a query on a dataset with a single time slot

[anikfal]

Trying to extract some data from a dataset that has only one single time slot:

>>> ncss.metadata.time_span
{'begin': '2001-01-01T00:00:00Z', 'end': '2001-01-01T00:00:00Z'}

If I set a time_range (e.g. time_start=2000-12-18T12%3A00%3A00&time_end=2001-02-14T12%3A00%3A00) including the time slot (2001-01-01T00:00:00), the query cannot run successfully:

>>> data = ncss.get_data(query)

However, if I redefine the query with no time_range, it can run successfully.

I transferred this to the TDS as it looks like it is an issue there and not with Siphon itself. I think I see the problem and a fix for it.

Hi @anikfal, the newest TDS 5.6-SNAPSHOT has the fix for this issue if you want to test it out!
