Clock.setCalibration

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.Clock.getTime] 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.Clock.getInternalTime] when this function is called.

Subsequent calls to [gst.clock.Clock.getTime] will return clock times computed as follows:

`` C time = (internal_time - internal) * rate_num / rate_denom + external ``

This formula is implemented in [gst.clock.Clock.adjustUnlocked]. Of course, it tries to do the integer arithmetic as precisely as possible.

Note that [gst.clock.Clock.getTime] always returns increasing values so when you move the clock backwards, [gst.clock.Clock.getTime] will report the previous value until the clock catches up.
