If we are not mentioning the Time.zone in the environment file , it will be UTC by default. I have mentioned config.active_record.default_time zone as :utc and this was working fine in ruby 1.8.7 but when i have changed that to ruby 1.9.2 its causing problems.

Answer 1

You have to set explicitly your time zone in you config file if you want to use Time.zone. There seems to be no default value.

In config/environment.rb:

Rails::Initializer.run do |config|
    config.time_zone = 'UTC'
end

To get a list of all available time zones with their UTC offset run

rake time:zones:all
