here is my gem:

gem 'mysql2', '>= 0.3'

is it my problem?

[mattconnolly]

It seems a change I made recently for improving date and time fields with mysql works only with the mysql gem and not the mysql2 gem.

Is it possible you can use the mysql gem instead of mysql2. This is something that should be fixed, but if you can change it temporarily it might mean that you can use it before i fix the issue.

Matt.

here is the fix I made:
