/**
* SECTION:gstclock
* @short_description: Abstract class for global clocks
* @see_also: #GstSystemClock
*
* GStreamer uses a global clock to synchronise the plugins in a pipeline.
* Different clock implementations are possible by implementing this abstract
* base class.
*
* The clock time is always measured in nanoseconds and always increases. The
* pipeline uses the clock to calculate the stream time.
* Usually all renderers sync to the global clock using the buffer timestamps,
* the newsegment events and the element's base time.
*
* The time of the clock in itself is not very usefull for an application.
