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.
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);
console.log(n.timestamp) // should log original timestamp
