The CalConnect TIMEZONE Technical Committee was originally chartered to develop problem statements and recommendations for managing time zone data in iCalendar, and recommendations for a TIMEZONE Registry and TIMEZONE service. The TC was reactivated in 2007 to develop the Time Zone Data Distribution Service specification, and to help progress it to a standard. The work of TC TIMEZONE was complete when the IETF published RFC 7808, Time Zone Data Distribution Service, and RFC 7809, Calendaring Extensions to Webdav - CalDAV: Time Zones by Reference.
CalConnect thanks all those who participated in the work of TC TIMEZONE, and those who participated in the work of the IETF TZDIST Working Group to progress these specifications to RFCs.
