# # == Introduction # # This library extends the Time class: # * conversion between date string and time object. # * date-time defined by RFC 2822 # * HTTP-date defined by RFC 2616 # * dateTime defined by XML Schema Part 2: Datatypes (ISO 8601) # * various formats handled by ParseDate (string to time only) # # == Design Issues # # === Specialized interface # # This library provides methods dedicated to special purposes: # * RFC 2822, RFC 2616 and XML Schema. # * They makes usual life easier. # # === Doesn't depend on strftime # # This library doesn't use +strftime+. Especially #rfc2822 doesn't depend # on +strftime+ because: # # * %a and %b are locale sensitive # # Since they are locale sensitive, they may be replaced to # invalid weekday/month name in some locales. # Since ruby-1.6 doesn't invoke setlocale by default, # the problem doesn't arise until some external library invokes setlocale. # Ruby/GTK is the example of such library. # # * %z is not portable # # %z is required to generate zone in date-time of RFC 2822 # but it is not portable. # # == Revision Information # # $Id$ # require 'parsedate' # # Implements the extensions to the Time class that are described in the # documentation for the time.rb library. # class Time class << Time ZoneOffset = { 'UTC' => 0, # ISO 8601 'Z' => 0, # RFC 822 'UT' => 0, 'GMT' => 0, 'EST' => -5, 'EDT' => -4, 'CST' => -6, 'CDT' => -5, 'MST' => -7, 'MDT' => -6, 'PST' => -8, 'PDT' => -7, # Following definition of military zones is original one. # See RFC 1123 and RFC 2822 for the error in RFC 822.
