title: mysql2 gem cause the 'utc' error when run on Rails3
body: <p>I run Rails app on Windows7.
  at first, I use Rails3 + Mysql2.
  but, cause an error when I test on console:</p>
  <blockquote>
  <p>rails console -s</p>
  <p>Photo.where(:id =&gt; 2)</p>
  </blockquote>
  <pre><code>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 `utc'
     
  </code></pre>
  <p>I'm sure that is mysql2's bug. because when I switch to mysql gem, everything runs ok.</p>
  <p>who can help me. thanks</p>
