Property Parameters: Non-standard, value data type, time zone identifier property parameters can be specified on this property. Conformance: This property can be specified in the "VEVENT", "VTODO", "VFREEBUSY", or "VTIMEZONE" calendar components. Description: Within the "VEVENT" calendar component, this property defines the start date and time for the event. The property is REQUIRED in "VEVENT" calendar components.
