Error when pushing data to Heroku: time zone displacement out of range
Using Ruby 1.9.2-p290 instead of 1.9.3-p0 fixed it for me. According to Roger Braun, this is the reason: The problem is (I think), that marshalling changed between Ruby 1.9.2 and 1.9.3, so this is not really a taps error. Just use whatever version heroku runs to push and pull databases (Probably 1.9.2).
