/*
 * Class method: new(clock, time, interval=nil)
 * clock: a Gst::Clock.
 * time: a time period, in nanoseconds.
 * interval: an interval period, in nanoseconds.
 *
 * Creates a new Gst::ClockEntry object based on the given Gst::Clock.
 *
 * Two types of Gst::ClockEntry objects can be created:
 *
 * * One-shot: if the interval is ommited or nil, the entry will trigger a single shot notification, at the requested time (in nanoseconds);
 * * Periodic: if the interval is not nil, the timer entry will trigger a periodic notification, starting at time (in nanoseconds), and be fired with the given interval (also in nanoseconds).
 * 
 * The timer will be issued after Gst::ClockEntry#wait or
 * Gst::ClockEntry#wait_async.
 *
 * Returns: a new Gst::ClockEntry object.
