This module is still very much experimental.

That means that WebRequest's events' 16 <code>timeStamp</code> property is only guaranteed to be <i>internally</i> 17 consistent. Comparing one event to another event will give you the correct 18 offset between them, but comparing them to the current time inside the 19 extension (via <code>(new Date()).getTime()</code>, for instance) might give 20 unexpected results. 21 </p> 22 <!-- END AUTHORED CONTENT --> 23
