httpdate 

        # Date.httpdate

(from ruby core)

    Date.httpdate(string='Mon, 01 Jan -4712 00:00:00 GMT'[, start=Date::ITALY], limit: 128)  ->  date

---

Creates a new Date object by parsing from a string according to some RFC
2616 format.

    Date.httpdate('Sat, 03 Feb 2001 00:00:00 GMT')
                                              #=> #<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.
