    /// GStreamer uses a global clock to synchronize the plugins in a pipeline.
    /// Different clock implementations are possible by implementing this abstract
    /// base class or, more conveniently, by subclassing `SystemClock`.
    ///
    /// The `Clock` returns a monotonically increasing time with the method
    /// `ClockExt::get_time`. Its accuracy and base time depend on the specific
    /// clock implementation but time is always expressed in nanoseconds. Since the
    /// baseline of the clock is undefined, the clock time returned is not
    /// meaningful in itself, what matters are the deltas between two clock times.
    /// The time returned by a clock is called the absolute time.
    ///
    /// The pipeline uses the clock to calculate the running time. Usually all
    /// renderers synchronize to the global clock using the buffer timestamps, the
    /// newsegment events and the element's base time, see `Pipeline`.
    ///
    /// A clock implementation can support periodic and single shot clock
    /// notifications both synchronous and asynchronous.
    ///
    /// One first needs to create a `ClockID` for the periodic or single shot
    /// notification using `ClockExt::new_single_shot_id` or
    /// `ClockExt::new_periodic_id`.
    ///
    /// To perform a blocking wait for the specific time of the `ClockID` use the
    /// `Clock::id_wait`. To receive a callback when the specific time is reached
    /// in the clock use `Clock::id_wait_async`. Both these calls can be
    /// interrupted with the `Clock::id_unschedule` call. If the blocking wait is
    /// unscheduled a return value of `ClockReturn::Unscheduled` is returned.
    ///
    /// Periodic callbacks scheduled async will be repeatedly called automatically
    /// until it is unscheduled. To schedule a sync periodic callback,
    /// `Clock::id_wait` should be called repeatedly.
    ///
    /// The async callbacks can happen from any thread, either provided by the core
    /// or from a streaming thread. The application should be prepared for this.
    ///
    /// A `ClockID` that has been unscheduled cannot be used again for any wait
    /// operation, a new `ClockID` should be created and the old unscheduled one
    /// should be destroyed with `Clock::id_unref`.
    ///
    /// It is possible to perform a blocking wait on the same `ClockID` from
    /// multiple threads. However, registering the same `ClockID` for multiple
    /// async notifications is not possible, the callback will only be called for
    /// the thread registering the entry last.
    ///
    /// None of the wait operations unref the `ClockID`, the owner is responsible
    /// for unreffing the ids itself. This holds for both periodic and single shot
    /// notifications. The reason being that the owner of the `ClockID` has to
    /// keep a handle to the `ClockID` to unblock the wait on FLUSHING events or
    /// state changes and if the entry would be unreffed automatically, the handle
    /// might become invalid without any notification.
    ///
    /// These clock operations do not operate on the running time, so the callbacks
    /// will also occur when not in PLAYING state as if the clock just keeps on
    /// running. Some clocks however do not progress when the element that provided
    /// the clock is not PLAYING.
    ///
    /// When a clock has the `ClockFlags::CanSetMaster` flag set, it can be
    /// slaved to another `Clock` with the `ClockExt::set_master`. The clock will
    /// then automatically be synchronized to this master clock by repeatedly
    /// sampling the master clock and the slave clock and recalibrating the slave
    /// clock with `ClockExt::set_calibration`. This feature is mostly useful for
    /// plugins that have an internal clock but must operate with another clock
    /// selected by the `Pipeline`. They can track the offset and rate difference
    /// of their internal clock relative to the master clock by using the
    /// `ClockExt::get_calibration` function.
    ///
    /// The master/slave synchronisation can be tuned with the `Clock:timeout`,
    /// `Clock:window-size` and `Clock:window-threshold` properties.
    /// The `Clock:timeout` property defines the interval to sample the master
    /// clock and run the calibration functions. `Clock:window-size` defines the
    /// number of samples to use when calibrating and `Clock:window-threshold`
    /// defines the minimum number of samples before the calibration is performed.
