For HTML downloaded (from the measure description details within AppMon):

Represents the amount of time spent until the document (HTML) was completely downloaded (window.performance.responseEnd - window.performance.navigationStart)

For DOM Complete (a standard W3C Timing):

DOM Complete time is the time elapsed from when the prompt to unload the previous document occurs until the time immediately before the document.readyState is set to complete. It is defined as:

timeToDomComplete =
performance.timing.domComplete - performance.timing.navigationStart

This W3C metric is calculated from events reported by the navigation timing API and interpreted by the W3C integration in the browser. In synthetic test results, one DOM Complete metric is reported, for the root object.
