[1] pry(main)> puts RUBY_VERSION
1.9.3
=> nil
[2] pry(main)> pre = Date.methods;
[3] pry(main)> pre.length
=> 104
[4] pry(main)> require 'date'
=> true
[5] pry(main)> post = Date.methods;
[6] pry(main)> post.length
=> 135
[7] pry(main)> intersection = pre & post;
[8] pry(main)> intersection.length
=> 104
[9] pry(main)> Object.methods.length
=> 104
[10] pry(main)> (intersection - Object.methods).length
=> 0

That's the extent of my 10-minute investigation. No idea why there'd be a Date class that has only the methods in Object.

Out of curiosity, was 135 the correct DOY when you pulled this?
