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.

The 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.

Syntax

var time = IntersectionObserverEntry.time;

Value

A 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.

Example

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.
