Description

By defining dataset.collection_date as the end of the collection period and standardizing the format, it becomes easy to filter/sort datasets based on collection date. Having a standard YYYY-mm-DD HH:MM:SS format where you can leave of least significant information accommodates almost all currently used collection_dates. Information about ranges could (for now) be moved into the description fields.

Research direction

Start by locating how dataset.collection_date is represented and processed in the server API, then review existing collection_date values and the description fields used for range information. Done means the end-of-period meaning and the standardized YYYY-mm-DD HH:MM:SS format are consistently defined and handled.
