DateTime-Format-Natural 0.22

on Perl CPAN

Previously four digits were occasionally interpreted as year
and as well as time based upon context. Disambiguated usage
as year (applies to all Lang:: classes) and fixed all test
cases were bogus return values from parse_datetime() have
been expected in order to have no tests fail.

Bound the temporary disablement of strictness for references
to a tighter scope (applies to all Lang:: classes).
