This can be tedious noise amongst your validations for something so common. To combat this the plugin allows you to use shorthand symbols for often used relative times or dates.

If you are using ActiveRecord then the default is automatically set to the same default zone as ActiveRecord. If you are using another ORM you may need to change this setting. +```ruby +# in the setup block +config.default_timezone = :utc +``` - # in the setup block - config.default_timezone = :utc +By default it will be `UTC` if ActiveRecord is not loaded. -By default it will be UTC if ActiveRecord is not loaded. - ### Dummy Date For Time Types Given that Ruby has no support for a time-only type, all time type columns are evaluated as a regular Time class objects with a dummy date value set. Rails defines the dummy date as 2000-01-01. So a time of '12:30' is evaluated as a Time value of '2000-01-01 12:30'.

This will add an error to the model such as 'Error occurred validating birth_date for :before restriction'. These can be annoying in development or production as you most likely just want to skip the option if no valid value was returned. By default these errors are displayed in Rails test mode.
