title: Mysql timezone on windows 7 not updated
body: <p>I'm using <strong>Windows 7</strong></p>
  
  <p><strong>Mysql 5.5.15</strong></p>
  
  <p>running <code>set time_zone = "Europe/Moscow";</code></p>
  
  <p>I get <code>Error Number: 1298
  Unknown or incorrect time zone: 'Europe/Moscow'</code></p>
  
  <p>I update the timezone tables using the latest from here <a href="http://dev.mysql.com/downloads/timezones.html">http://dev.mysql.com/downloads/timezones.html</a>
  but after mysql server startup the time zone tables are still empty and the command still returns the same errors.</p>
  
  <p>Does anyone faced similar problem?</p>
