The High Resolution Time spec [1] provides a monotonically increasing, sub-millisecond API as well as new type DOMHighResTimeStamp (which is really just a double). Given the performance-y nature of these stats, perhaps creationDate can be similar to window.performance.now() in that it's a time value measured relative to navigationStart [2].

Adrian: Do you have any reason to prefer Date() over DOMHighResTimeStamp? If we change the type here then we should probably rename the attribute to creationTime. 87273 2 adrianba 2013-05-06 17:34:11 +0000 (In reply to comment #1) > Adrian: Do you have any reason to prefer Date() over DOMHighResTimeStamp?
