Adjusts the rate and time of @clock. A rate of 1/1 is the normal speed of
the clock. Values bigger than 1/1 make the clock go faster.
@internal and @external are calibration parameters that arrange that
gst_clock_get_time() should have been @external at internal time @internal.
This internal time should not be in the future; that is, it should be less
than the value of gst_clock_get_internal_time() when this function is called.
Subsequent calls to gst_clock_get_time() will return clock times computed as
follows:
This formula is implemented in gst_clock_adjust_unlocked(). Of course, it
tries to do the integer arithmetic as precisely as possible.
Note that gst_clock_get_time() always returns increasing values so when you
move the clock backwards, gst_clock_get_time() will report the previous value
until the clock catches up.
