Are there any plugins that allow one to make use of the _trackPageLoadTime(); functionality available in the new version of Google Analytics yet?
Google Analytics by Yoast has Custom Code setting to add stuff to tracking code. But says that it is added before
trackPageview, while site speed instructions show it added after. Might or might not matter, I don't know.
Plugin has been updated to support (and default to) site speed tracking.
Why not just include the google analytics code in the functions file by hooking wp_foot? I usually just add it that way. Are you trying to use something like Analyticator that shows the analytics on your dashboard?
You can download it on GitHub: C3M Google Analytics
Google Analyticator has always had the option to add code before, or after initialization. We use it on all our sites and it's working great.
