Bug #634
closedTime parsing works in 1.8 but not 1.9
Description
=begin
This works in 1.8, but results in "ArgumentError: argument out of range" in 1.9:
require 'time'
Time::parse('06/21/95 04:24:34 PM')
=end

seems that Date is similarly broken on 1.9, working on 1.8
require 'date'
Date::parse('06/21/95')
~ ruby19 test.rb
/Users/rogerpack/dev/ruby_19_installed/lib/ruby/1.9.0/date.rb:1022:in new_by_frags': invalid date (ArgumentError) from /Users/rogerpack/dev/ruby_19_installed/lib/ruby/1.9.0/date.rb:1066:in
parse'
from test.rb:2:in `'

Seems somewhat surprising to me that
Date::parse('06/21/95')
doesn't parse, though I suppose that's better than what 1.8.x currently does:
irb(main):004:0> Date.parse("08/21/97").to_s
=> "0097-08-21"
Which is definitely bad :)
Should I file these as feature requests to have them work [and guess century].
Also should I file a feature request to change Time.parse to raise on
failed parse instead of returning Time.now [as you can't currently
determine if a time parsed successfully or not--at least not easily].
Thanks!

"dd/dd/dd" format itself is very culture dependent and ambiguous. It
is yy/mm/dd in Japan (and other countries), mm/dd/yy in USA, dd/mm/yy
in European countries, right? In some cases, you can tell them by
accident, but we should not rely on luck in general cases. I believe
that is the reason parsing this format is disabled in 1.9.

It seems reasonable. You can file a feature request for this issue.

should Date.parse("4/30/2009")
parse in 1.9?
Date.parse("4/30/2009")
ArgumentError: invalid date
...
Thanks!
