Ruby on Rails time zone

The following are all the timezones in Ruby on Rails 3  (as of Rails 3.0.5)

We can set it in config/application.rb, as

config.time_zone = 'Pacific Time (US & Canada)'

Note that it needs to be the exact string -- if we use:

config.time_zone = 'Pacific Time'      # NOT GOOD

it will stop the server from starting up.

The line Time.zone = 'Pacific Time (US & Canada)'   can change the time zone in view, but in the controller, the time zone will still be UTC.

The way to get all Time Zones in Rails is:


$ rake time:zones:all
