Description

Mediawiki time parser function silently "mitigates" incorrect date (with day > max month days (in given year) and ≤ 31) by wrapping days into next month,
e.g.:

{{#time:Y-m-d|2001-02-29}} ⇒ 2001-03-01
{{#time:Y-m-d|2000-02-30}} ⇒ 2000-03-01
{{#time:Y-m-d|2000-02-31}} ⇒ 2000-03-02
{{#time:Y-m-d|2001-02-31}} ⇒ 2001-03-03
{{#time:Y-m-d|2000-04-31}} ⇒ 2000-05-01
{{#time:Y-m-d|2000-06-31}} ⇒ 2000-07-01
{{#time:Y-m-d|2000-09-31}} ⇒ 2000-10-01
{{#time:Y-m-d|2000-11-31}} ⇒ 2000-12-01

vs e.g.:

{{#time:Y-m-d|2000-01-32}} ⇒ Error: Invalid time.
