Date#rfc822

d.rfc822 → string

Alias of #rfc2822

Creates a new Date object by parsing from a string according to some typical RFC 2822 formats.

Example
Date.rfc2822('Sat, 3 Feb 2001 00:00:00 +0000')
                                          #=> #<Date: 2001-02-03 ...>

Raise an ArgumentError when the string length is longer than limit. You can stop this check by passing ‘limit: nil`, but note that it may take a long time to parse.
