[Time] Format `YYYY-Month-DD` does not get properly extracted.

Hi, thanks for this great library! I've noticed an issue related to time parsing. Dates of the format `YYYY-Month-DD`, e.g. `2019-Feb-21` do not get properly extracted. Two issues:
- The year is extracted as a number, and not as a part of the date. So `2019-Feb-21` gives two entities: `2019` (number) and `Feb-21` (date).
- Even when just considering the date that gets extracted, that date is wrong. For instance, `2017-Dec-18` gets extracted to `01/12/1982`.

No file or test entry point is named in the issue. Reproduce the examples `2019-Feb-21` and `2017-Dec-18`, then locate the time-parsing rules and their existing tests; done means the full input is extracted as one date and resolves to the correct year, month, and day.
