Notification: timestamp property
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
Note: This feature is available in Web Workers.
The timestamp
read-only property of the
Notification
interface returns a number, as
specified in the timestamp
option of the
Notification()
constructor.
The notification's timestamp can represent the time, in milliseconds since 00:00:00 UTC on 1 January 1970, of the event for which the notification was created, or it can be an arbitrary timestamp that you want associated with the notification. For example, a timestamp for an upcoming meeting could be set in the future, whereas a timestamp for a missed message could be set in the past.
Value
A number representing a timestamp, given as Unix time in milliseconds.
Examples
The following snippet fires a notification; a simple options
object is
created, then the notification is fired using the Notification()
constructor.
const dts = Math.floor(Date.now());
const options = {
body: "Your code submission has received 3 new review comments.",
timestamp: dts,
};
const n = new Notification("New review activity", options);
console.log(n.timestamp); // Logs the timestamp
