-/// Get a Tm from HTTP date formats.
-//    Prior to 1995, there were three different formats commonly used by
-//   servers to communicate timestamps.  For compatibility with old
-//   implementations, all three are defined here.  The preferred format is
-//   a fixed-length and single-zone subset of the date and time
-//   specification used by the Internet Message Format [RFC5322].
-//
-//     HTTP-date    = IMF-fixdate / obs-date
-//
-//   An example of the preferred format is
-//
-//     Sun, 06 Nov 1994 08:49:37 GMT    ; IMF-fixdate
-//
-//   Examples of the two obsolete formats are
-//
-//     Sunday, 06-Nov-94 08:49:37 GMT   ; obsolete RFC 850 format
-//     Sun Nov  6 08:49:37 1994         ; ANSI C's asctime() format
-//
-//   A recipient that parses a timestamp value in an HTTP header field
-//   MUST accept all three HTTP-date formats.  When a sender generates a
-//   header field that contains one or more timestamps defined as
-//   HTTP-date, the sender MUST generate those timestamps in the
-//   IMF-fixdate format.
