# == 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 Date._parse (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.
#

#
# Parses +date+ using Date._parse and converts it to a Time object.
#
# If a block is given, the year described in +date+ is converted by the
# block. For example:
#
# Time.parse(...) {|y| y < 100 ? (y >= 69 ? y + 1900 : y + 2000) : y}
#
# If the upper components of the given time are broken or missing, they are
# supplied with those of +now+. For the lower components, the minimum
# values (1 or 0) are assumed if broken or missing. For example:
#
# # Suppose it is "Thu Nov 29 14:33:20 GMT 2001" now and
# # your timezone is GMT:
# Time.parse("16:30") #=> Thu Nov 29 16:30:00 GMT 2001
# Time.parse("7/23") #=> Mon Jul 23 00:00:00 GMT 2001
# Time.parse("Aug 31") #=> Fri Aug 31 00:00:00 GMT 2001
#
# Since there are numerous conflicts among locally defined timezone
# abbreviations all over the world, this method is not made to
# understand all of them. For example, the abbreviation "CST" is
# used variously as:
#
# -06:00 in America/Chicago,
# -05:00 in America/Havana,
# +08:00 in Asia/Harbin,
# +09:30 in Australia/Darwin,
# +10:30 in Australia/Adelaide,
# etc.
#
# Based on the fact, this method only understands the timezone
# abbreviations described in RFC 822 and the system timezone, in the
# order named. (i.e. a definition in RFC 822 overrides the system
# timezone definition.) The system timezone is taken from
# <tt>Time.local(year, 1, 1).zone</tt> and
# <tt>Time.local(year, 7, 1).zone</tt>.
# If the extracted timezone abbreviation does not match any of them,
# it is ignored and the given time is regarded as a local time.
#
# ArgumentError is raised if Date._parse cannot extract information from
# +date+ or Time class cannot represent specified date.
#
# This method can be used as fail-safe for other parsing methods as:
#
# Time.rfc2822(date) rescue Time.parse(date)
# Time.httpdate(date) rescue Time.parse(date)
# Time.xmlschema(date) rescue Time.parse(date)
#
# A failure for Time.parse should be checked, though.
