= time

This library extends 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 format handled by ParseDate. (string to time only)

== Design Issue

* specialized interface

  This library provides methods dedicated to special puposes:
  RFC 2822, RFC 2616 and XML Schema.
  They makes usual life easier.

* doesn't depend on strftime

  This library doesn't use strftime.
  Especially Time#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.

== class methods

--- Time.parse(date, now=Time.now)
--- Time.parse(date, now=Time.now) {|year| year}
    parses ((|date|)) using ParseDate.parsedate 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("2002/1")    #=> Tue Jan 01 00:00:00 GMT 2002

    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
    (({Time.local(year, 1, 1).zone})) and
    (({Time.local(year, 7, 1).zone})).
    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 ParseDate 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.
