 | autoTrackPageVisitTime | boolean | false | If true, on a pageview, the _previous_ instrumented page's view time is tracked and sent as telemetry and a new timer is started for the current pageview. It is sent as a custom metric named `PageVisitTime` in `milliseconds` and is calculated via the Date [now()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/now) function (if available) and falls back to (new Date()).[getTime()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getTime) if now() is unavailable (IE8 or less).
