This module parses and prints RFC 1123 Date and Time string.
In general you don't have to use this module directly.
System.Time.CalendarTime to RFC 1123 Date and Time
System.Time.ClockTime to HTTP Date and Time. Time zone
will be always UTC but prints as GMT.
Parse an HTTP Date and Time.
Limitation: RFC 2616 (HTTP/1.1) says we must accept these three formats:
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
...but currently this function only supports the RFC 1123 format. This is a violation of RFC 2616 so this should be fixed later. What a bother!
