wrong display of century dates

[Nono314]

follow-up to #10

examples at https://www.wikidata.org/wiki/Wikidata:WikiProject_sum_of_all_paintings/Collection/Georgia_Museum_of_Art : dates listed as 19th century when they are actually 20th century (creator was merely a toddler at end of 19th century).

I see the same [https://nl.wikipedia.org/wiki/Gebruiker%3ARonnieV%2FOntbrekende_Benelux-kunstenaars_overleden_in_1950] here.
It would also be great if it would be possible to exclude century-dates (20th century) from dates in the year ..50, whilst selecting with
FILTER ( year(?date) = 1950 )
or
FILTER ( ?date >= "1950-01-01T00:00:00Z"^^xsd:dateTime && ?date < "1950-12-31T23:59:59Z"^^xsd:dateTime )
A clue for this is welcome as well.

@Ronnie-V for the last point, this is query-specific. You can filter on wikibase:timePrecision (see https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#Time) if needed.
