-  A brief summary of the date string formats this parser groks:
-
-  RFC 2616 3.3.1
-
-  Sun, 06 Nov 1994 08:49:37 GMT  ; RFC 822, updated by RFC 1123
-  Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036
-  Sun Nov  6 08:49:37 1994       ; ANSI C's asctime() format
-
-  we support dates without week day name:
-
-  06 Nov 1994 08:49:37 GMT
-  06-Nov-94 08:49:37 GMT
-  Nov  6 08:49:37 1994
-
-  without the time zone:
-
-  06 Nov 1994 08:49:37
-  06-Nov-94 08:49:37
-
-  weird order:
-
-  1994 Nov 6 08:49:37  (GNU date fails)
-  GMT 08:49:37 06-Nov-94 Sunday
-  94 6 Nov 08:49:37    (GNU date fails)
-
-  time left out:
-
-  1994 Nov 6
-  06-Nov-94
-  Sun Nov 6 94
-
-  unusual separators:
-
-  1994.Nov.6
-  Sun/Nov/6/94/GMT
-
-  commonly used time zone names:
-
-  Sun, 06 Nov 1994 08:49:37 CET
-  06 Nov 1994 08:49:37 EST
-
-  time zones specified using RFC822 style:
-
-  Sun, 12 Sep 2004 15:05:58 -0700
-  Sat, 11 Sep 2004 21:32:11 +0200
-
-  compact numerical date strings:
