How to save a timezone correctly with Ruby and MongoId?
It looks like you need to specify the field type of your date attribute. I would use a Time field if you want mongoid to handle the zones properly.
class Lineup include Mongoid::Document field :date, type: TimeendYou will also probably want to set the following in config/mongoid.yml
defaults: &defaults use_utc: false use_activesupport_time_zone: trueThis sounds counterintuitive, but this is the current way to make mongoid use UTC as the default timezone.
Finally, have a look at the mongoid-metastamp gem. It will give you much better support for querying across multiple timezones, while still seamlessly working like a native Time field.
