At least a very simple subset of https://www.loc.gov/standards/datetime/ should be supported, e.g.

Uncertain/Approximate such as 1922~ or 2014-12?
Unspecified, such as 199u or 2014-12-uu
Year Exceeding Four Digits for year only values, e.g. y-117000
Examples

{
  "id": "http://www.wikidata.org/entity/Q25445",
  "prefLabel": { "en": "Holocene" },
  "startDate": "y-117000",
  "previous": [{"id":"http://www.wikidata.org/entity/Q25546"}]
}
