timestamp

This article needs a technical review. How you can help.

The timestamp read-only property of the Notification interface returns a DOMTimeStamp, 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.

Note: This feature is available in Web Workers.

Syntax

var timestamp = Notification.timestamp;

Value

A DOMTimeStamp.

Examples

The following snippet fires a notification; a simple options object is created, then the notification is fired using the Notification() constructor.

var dts = Math.floor(Date.now());

var options = {
  body: 'Do you like my body?',
  timestamp: dts
}

var n = new Notification('Test notification',options);

n.timestamp // should return original timestamp
