Hi -- I'm noticing this change, and wondering about it: irb(main):001:0> RUBY_VERSION => "1.8.6" irb(main):002:0> require 'date' => true irb(main):003:0> puts Date.parse("1/2/3").mon 1 irb(main):001:0> RUBY_DESCRIPTION => "ruby 1.9.0 (2008-11-12 revision 20227) [i386-darwin9.5.0]" irb(main):002:0> require 'date' => true irb(main):003:0> puts Date.parse("1/2/3").mon 2 Am I neglecting to set something I should be setting to get US behavior in 1.9?
