2.1.3.1.1.19.2 Component: STANDARD
RFC Reference: [RFC2445] section 4.6.5
Number of Instances Allowed: 1+
Brief Description: A specification of the Standard portion of the time zone.
Importing to Calendar objects
If more than one STANDARD component is defined in the VTIMEZONE, only the STANDARD component with the largest DTSTART (as specified in section 2.1.3.1.1.19.2.1) SHOULD<50> be parsed. Alternatively, implementers MAY<51> parse the first STANDARD component found within the VTIMEZONE, MAY<52> parse all STANDARD components found within the VTIMEZONE that have unique years in their DTSTART subcomponents, or MAY<53> fail to parse the iCalendar stream if more than one STANDARD component is defined in the VTIMEZONE.
Exporting from Calendar objects
Exactly one STANDARD component SHOULD be exported for each VTIMEZONE.
