I hadn't. Hmm, looks like I should...

I'll give it a go once #21 is merged.

Hasn't #21 (or #22 relatively) been merged quite a while ago? 😉

There is this library you could use to still have support for older browsers without the performance API (http://caniuse.com/#feat=user-timing). This lib would additionally add support for using tock in pure node environments.

Pull requests are accepted ;)

I'll see if I can find some time to look into this soon. Thanks for the link.
