[!WARNING] This interface of this property is deprecated in the Navigation Timing Level 2 specification. Please use the {{domxref("PerformanceNavigationTiming")}}  interface instead.

The legacy PerformanceTiming.domLoading read-only property returns an unsigned long long representing the moment, in milliseconds since the UNIX epoch, when the parser started its work, that is when its {{domxref("Document.readyState")}}  changes to 'loading' and the corresponding {{domxref("Document/readystatechange_event", "readystatechange")}}  event is thrown.

Value

An unsigned long long.
