mysql2 gem cause the 'utc' error when run on Rails3

I run Rails app on Windows7. at first, I use Rails3 + Mysql2. but, cause an error when I test on console:

rails console -s

Photo.where(:id => 2)

ArgumentError: argument out of range
    from C:/Ruby192/lib/ruby/gems/1.9.1/gems/mysql2-0.2.6-x86-mingw32/lib/active_record/connection_adapters/mysql2_adapter.rb:640:in `开发者_运维技巧utc'
   

I'm sure that is mysql2's bug. because when I switch to mysql gem, everything runs ok.

who can help me. thanks
