This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
IntersectionObserverEntry interface's read-only
time property is a
DOMHighResTimeStamp that indicates the time at which the intersection change occurred relative to the time at which the document was created.
var time =IntersectionObserverEntry.time;
DOMHighResTimeStamp which indicates the time at which the
target element experienced the intersection change described by the
IntersectionObserverEntry. The time is specified in milliseconds since the creation of the containing document.
See Timing element visibility with the Intersection Observer API for a complete example which uses the
time property to track how long elements are visible to the user.
The definition of 'IntersectionObserverEntry.time' in that specification.
