Summary: We should try to be compliant with the Darwin Core eventDate for reduced precision dates 
Priority: Major
Status: Open
Created: 2013-01-24 12:18:53.23

Description: The interpretation of reduced precision dates in raw_occurrence table, like; Year = 2009 , Month = 08 , Day = NULL only retains the year value.
We should be able to parse the date values listed here: http://code.google.com/p/darwincore/wiki/Event (to the extent that it is possible - interval dates might be excepted)

Portal record:
http://data.gbif.org/occurrences/144028409

Raw_occurrence_record sample:
(id, collection, scientific_name, year, month)
144028409	Invertebrate Zoology: Mollusks	Cerithium Thericium columna	1966	7

(The year and month value also appear in the occurrence_record table.)

As you can see the month value is purged in the final presentation.]]>
