PerformanceElementTiming: presentationTime property

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The presentationTime read-only property of the PerformanceElementTiming interface returns the timestamp when the element was actually drawn on the screen.

The presentationTime is optional — some browsers may choose always to return 0 or not to expose the value at all. The value is also implementation-dependent — it may differ across browsers that choose to expose it.
