Cogl.FrameInfo.prototype.get_presentation_time
function get_presentation_time(): Number(gint64) { // Gjs wrapper for cogl_frame_info_get_presentation_time() }
Gets the presentation time for the frame. This is the time at which the frame became visible to the user.
The presentation time measured in nanoseconds is based on a monotonic time source. The time source is not necessarily correlated with system/wall clock time and may represent the time elapsed since some undefined system event such as when the system last booted.
<note>Linux kernel version less that 3.8 can result in non-monotonic timestamps being reported when using a drm based OpenGL driver. Also some buggy Mesa drivers up to 9.0.1 may also incorrectly report non-monotonic timestamps.</note>
Since 1.14
- Returns
the presentation time for the frame
