Date parsing for date ranges

[M-Nicholls]

dd-mm-yyyy/dd-mm-yyyy doesn't parse in the eventDate field
yyyy-mm-dd/yyyy-mm-dd does parse correctly

capability to cater for start and end dates as separate fields on ingest would be useful e.g. startEventDate endEventDate. Values would not be stored but would be converted to a single properly formatted eventDate field for ingest.

Darwin Core specifies eventDate as being ISO8601. It might be simpler to clean up the dates prior to loading rather than adding non-ISO8601 parsing logic to biocache-store.

this should just be another format to add to the existing dateparser.

[djtfmartin]

was there a conclusion to this one @ansell @M-Nicholls ?

[ansell]

I haven't looked into any of the date parsing, including the non-compliant date ranges noted here. One user noted that even parsing valid ISO8601 date ranges is broken though, filed separately as #245

This is fixed on 2.x
