OpenAtlas

Should be possible, will look into it.

Edited If sorting ascending, the entity with the "oldest" date will come first, sorting descending, the entity with the "youngest" date will be first. All entities without any date will come last, doesn't matter if asc or desc.

Right now, entities without a date get a temporary fictional date of (-)9999999-01-01T00:00:00. If we somehow get dates before that, we have to change this.
