is set to the literal start of the month and the end is set to the literal end
of the month.

> Key: CLIMATE-338
> URL: https://issues.apache.org/jira/browse/CLIMATE-338
> Project: Apache Open Climate Workbench
> Issue Type: Bug
> Components: data sources
> Affects Versions: 0.3-incubating
> Reporter: Michael Joyce
> Assignee: Michael Anderson
> Priority: Major
> Fix For: 1.3.0
>
> Attachments: test.py
>
>
> When trying to load a dataset with `data_source.rcmed` where the time values
> don't fall on the first of the month the end time is not properly bounded.
> Consider CRU31, where the day values fall on the 15th of the month. Notice
> that the returned end time is not properly bounded by the passed end time.
> CRU31
> Passed start time: 1901-02-01 00:00:00
> Returned start time: 1901-02-15 00:00:00
> Passed end time: 1901-04-01 00:00:00
> Returned end time: 1901-04-15 00:00:00
> However, on TRMM, where the time values fall on the first, the values are
> properly bounded.
> TRMM
> Passed start time: 1998-02-01 00:00:00
> Returned start time: 1998-02-01 00:00:00
> Passed end time: 1998-03-01 00:00:00
> Returned end time: 1998-03-01 00:00:00
