Date() is suspect to changes in system clock and/or clock skew. 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].
