W3C User Timing in Google Analytics: setup of Patrick Meenans support routine

Could somebody guide me with usage of Patrick Meenans support routine for adding W3C user timing events to Google Analytics, Support routine for adding W3C user timing events to a site. Includes some basic polyfill support for browsers that don't support user timing or navigation timing (though the start time for non-navigation timing support could be improved with IE < 9 to use IE's custom start event). · GitHub ?

Particular questions are:

  • How / where to implement scripts from Gist?
  • What to setup inside of GA?
