Time is wrong

[tomlarkworthy]

This is not the correct conversion to millis:
var clocktime = performanceNow.call(performance)/10e3

divide by 1e3 or multiple by *0.001 (computationally cheaper)

A pretty serious bug for a library that is polyfilling an accurate timer :s
Maybe write some tests?

Notices a few more bugs, 10e9 where you mean 1e9. I think you have got confused over e notation.
