PressureRecord: time property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
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
}
