> While casting a string to a date with a custom date format having day token before year
and moth tokens, the date is parsed incorrectly for leap days.
> h3. How to reproduce
> Execute {code}select cast("29 02 0" as date format "dd mm rr"){code} with Hive. The query
 results in *2020-02-28*, incorrectly.
> ----
> Executing the another cast with a slightly modified representation of the date (day is
preceded by year and moth) is however correctly parsed:
> {code}select cast("0 02 29" as date format "rr mm dd"){code}
> It returns *2020-02-29*.
