Ruby on Rails Change default timezone
Remarks
config.active_record.default_timezone determines whether to use Time.local (if set to :local) or Time.utc (if set to :utc) when pulling dates and times from the database. The default is :utc. http://guides.rubyonrails.org/configuring.html
If you want to change Rails timezone, but continue to have Active Record save in the database in UTC, use
# application.rb
config.time_zone = 'Eastern Time (US & Canada)'
If you want to change Rails timezone AND have Active Record store times in this timezone, use
# application.rb
config.time_zone = 'Eastern Time (US & Canada)'
config.active_record.default_timezone = :local
Warning: you really should think twice, even thrice, before saving times in the database in a non-UTC format.
Note
Do not forget to restart your Rails server after modifyingapplication.rb.
Remember that config.active_record.default_timezone can take only two values
- :local (converts to the timezone defined in
config.time_zone) - :utc (converts to UTC)
Here's how you can find all available timezones
rake time:zones:all
