Class: Icalendar::Timezone

A Timezone is unambiguously defined by the set of time measurement rules determined by the governing body for a given geographic area. These rules describe at a minimum the base offset from UTC for the time zone, often referred to as the Standard Time offset. Many locations adjust their Standard Time forward or backward by one hour, in order to accommodate seasonal changes in number of daylight hours, often referred to as Daylight Saving Time. Some locations adjust their time by a fraction of an hour. Standard Time is also known as Winter Time. Daylight Saving Time is also known as Advanced Time, Summer Time, or Legal Time in certain countries. The following table shows the changes in time zone rules in effect for New York City starting from 1967. Each line represents a description or rule for a particular observance.

Public Class methods

new(name = "VTIMEZONE")

[Source]

# File lib/icalendar/component/timezone.rb, line 62
    def initialize(name = "VTIMEZONE")
      super(name)
    end

Public Instance methods

add_component(component)

Define a custom add component method because standard and daylight are the only components that can occur just once with their parent.

[Source]

# File lib/icalendar/component/timezone.rb, line 44
    def add_component(component)
      key = component.class.to_s.downcase.gsub('icalendar::','').to_sym
      @components[key] = component
    end

daylight(&block)

[Source]

# File lib/icalendar/component/timezone.rb, line 76
    def daylight(&block)
      e = Daylight.new
      self.add_component e

      e.instance_eval &block if block

      e
    end

standard(&block)

Allow block syntax for declaration of standard and daylight components of timezone

[Source]

# File lib/icalendar/component/timezone.rb, line 67
    def standard(&block)
      e = Standard.new
      self.add_component e

      e.instance_eval &block if block

      e
    end

to_ical()

Also need a custom to_ical because typically it iterates over an array of components.

[Source]

# File lib/icalendar/component/timezone.rb, line 51
    def to_ical
      print_component do
      s = ""
        @components.each_value do |comp|
          s << comp.to_ical
        end
      s
      end
    end
