Everything happens in UTC!
Thats the one basic thing you must know about handling Times in Rails.
SomeModel.create(:time_attribute => Time.now) SomeModel.create(:time_attribute => Time.zone.now)
Both lines will insert the same value into the database –> UTC+0. ActiveRecord will automaticly convert the given time. Therefore the
application.rb only controlls the default timezone and not the Timezone format the database will store the attribute.
You can also safely compare times that are in different zones – you don’t need to convert them to some common timezone.
A good link I found while adding time zones to our own project was this: http://www.redguava.com.au/2010/12/rails-basics-handling-user-timezones-in-rails/
