The nsIDOMHTMLTimeRanges interface represents a set of time ranges in media; it's primarily used by the nsIDOMHTMLMediaElement interface, and implements the DOM TimeRanges interface.
Each time range represented by an nsIDOMHTMLTimeRanges object has an index number; you call the start() and end() methods to obtain the start and end times of each range, specifying the index number of the range to look up.
