The read-only time property returns the timestamp recorded for a PressureRecord. It corresponds to the time the data was obtained from the system relative to the time origin of the global object in which the PressureObserver generated the notification.

Value

A DOMHighResTimeStamp representing the timestamp when the PressureRecord was created.

Examples

Using the `time` property

In the following example we log the value of the time property in the pressure observer callback.

function callback(records) {
  const lastRecord = records[records.length - 1];
  console.log(`Current pressure ${lastRecord.state}`);
  console.log(`Current pressure observed at ${lastRecord.time}`);
}

try {
  const observer = new PressureObserver(callback);
  await observer.observe("cpu", {
    sampleInterval: 1000, // 1000ms
  });
} catch (error) {
  // report error setting up the observer
}
