datetimes nil in ActiveRecord, but present in database?

Can you guys see here:

http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/251ff7b5a1dce93a/50e40fbb176f4b79

I'm totally at a loss. Running rails 2.3.5, ruby 1.8.7 enterprise,
mysql 5.0.77

All datetimes (created_at, updated_at, any others that I've added) are
nil via my remote webserver, yet they're present in the console.
They're also present in the database. They're also present via
@model.created_at_before_type_cast

Everything works flawlessly on my local macbook.

Advice/Help please?!

Thanks,
Jeff

Nevermind all:

I was also setting ActiveRecord::Base.default_timezone in my
application_controller, likely to a value other than the symbol :utc.
Removing this fixed it.
