> GStreamer can use different clocks. Though the system time can be used
as a clock, soundcards and other devices provides a better time source. For
this reason some elements provide a clock. The method
<CODE
CLASS="function"
>get_clock</CODE
> is implemented in elements that provide
one.
</P
><P
> As clocks return an absolute measure of time, they are not usually used
directly. Instead, a reference to a clock is stored in any element that needs
it, and it is used internally by GStreamer to calculate the element time.
