Subject: [ruby-talk:14652] I can't use -w because of date.rb

Let's try something less controversial...

I can't use the 'ruby -w' any programs that use the Date module
included with ruby.

An example:

$ ruby -v
ruby 1.6.3 (2001-03-28) [i386-linux]
$ ruby -w
require "date"
Date.new(2003,3,4).cwyear
^D
(eval):4: warning: instance variable @__9569__ not initialized
(eval):4: warning: instance variable @__9041__ not initialized

$ /usr/local/bin/ruby -v
ruby 1.7.0 (2001-05-02) [i686-linux]
$ /usr/local/bin/ruby -w
require "date"
Date.new(2003,3,4).cwyear
^D
(eval):4: warning: instance variable @__9785__ not initialized
(eval):4: warning: instance variable @__9257__ not initialized


Those warning come anytime the library is used.


Suggestions:

I would love it if the builtin Time class included a 'parse' method
that worked like ParseDate, but did timezones correctly.  As far as I
can tell you can't create a Time object with a zone other than local
or GMT.  (*)

I also want to be able to get workweek and year from a Time.  (cwday,
cweek in Date)

* I found this in the archives:

require 'parsedate'
class Time
  def Time.parse( timestr )
    year, month, day, hour, min, sec, zone, wday = 
      ParseDate.parsedate( timestr )
    tm = Time.gm( year, month, day, hour, min, sec )
    return tm  unless zone
    return tm  if zone.to_i == 0

    hour = zone[0,3].to_i * 3600
    min  = zone[3,2].to_i * 60
    ofs  = (hour + min)
    return Time.at( tm.to_f - ofs )
  end
end

Perhaps this should be added to parsedate.

It still fails in the timezone is a string.
