I just went through and followed this for a Rails 3.1.1 app. It was a great help with the appropriate pointers. What I found with my 3.1.1 usage was:
1) I had to adjust the config/environment.rb line(s).
config.time_zone = "Eastern Time (US & Canada)"
2) I am using simple form and found that just <%= f.input :time_zone %> does the automagic for me, which was a treat
Thanks for the great content! The 'classic' episodes remain a useful reference.
