rfc2822 

        # Time.rfc2822

(from ruby core)
---
    rfc2822(date)

---

Parses `date` as date-time defined by RFC 2822 and converts it to a Time
object.  The format is identical to the date format defined by RFC 822
and updated by RFC 1123.

ArgumentError is raised if `date` is not compliant with RFC 2822 or if
the Time class cannot represent specified date.

See #rfc2822 for more information on this format.

    require 'time'

    Time.rfc2822("Wed, 05 Oct 2011 22:26:12 -0400")
    #=> 2010-10-05 22:26:12 -0400

You must require 'time' to use this method.


(from ruby core)
---
    rfc2822()

---

Returns a string which represents the time as date-time defined by RFC
2822:

    day-of-week, DD month-name CCYY hh:mm:ss zone

where zone is [+-]hhmm.

If `self` is a UTC time, -0000 is used as zone.

    require 'time'

    t = Time.now
    t.rfc2822  # => "Wed, 05 Oct 2011 22:26:12 -0400"

You must require 'time' to use this method.
