Dont forget to load the rails timezones!
February 14, 2011
If your migrate to a new mysql database server and your information relies on dates and timezones, specially if you use the mysql timezone functions such as CONVERT_TZ then dont forget to load time zones into your rails db
If you are using ubuntu this works just fine:
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql
