I have a Rails application with a default time zone of UTC. This works fine for almost everything. Now I have a situation where I would like to present the values in a datetime_select offset by a specific time zone. As far as I know, this helper does not have an option to specify the time zone that is used when persisting this data. When the form is submitted, it only sends the year, month, day, hour, and minute fields. ActiveRecord is responsible for converting these values into the time zone configured for the application. In this case, I want to change the time zone for only these fields so that it is localized to the user (but still store the correct UTC time). How can I make this change?
