gdk:frame-clock-frame-time (clock)

clock -- a gdk:frame-clock object

The integer with a timestamp in microseconds.

Gets the time that should currently be used for animations. Inside the processing of a frame, it is the time used to compute the animation position of everything in a frame. Outside of a frame, it is the time of the conceptual "previous frame", which may be either the actual previous frame time, or if that is too old, an updated time.
