class ActiveModel::Type::Time
Active Model
Time Type¶ ↑
Attribute
type for time of day representation. It is registered under the :time
key.
class Event include ActiveModel::Attributes attribute :start, :time end
String
values are parsed using the ISO 8601 datetime format, but are normalized to have a date of 2000-01-01 and be in the UTC time zone.
event = Event.new event.start = "2004-10-25T01:23:45-06:00" event.start.class # => Time event.start # => 2000-01-01 07:23:45 UTC
Partial time-only formats are also accepted.
event.start = "00:01:02+03:00" event.start # => 1999-12-31 21:01:02 UTC
The degree of sub-second precision can be customized when declaring an attribute:
class Event include ActiveModel::Attributes attribute :start, :time, precision: 4 end
