I'm not sure why you are looking for a hash.

data = [
[ "model1", "instance of 1", Time.now],
[ "model2", "instance of 2", Time.now - 100]
]

p data.sort_by { |x| x[2] }   # => [["model2", "instance of 2", Sat  
Dec 08 17:15:41 -0500 2007], ["model1", "instance of 1", Sat Dec 08  
17:17:21 -0500 2007]]
