Disqus client-side session id generating function

generate-session-id.js

function generateSessionId() {
    // remove 3 most significant digits as they don't change often
    var time = +(new Date().getTime().toString().substring(3));

    // Doing only arithmetic operations here as bitwise shifts only operate on int32.
    // Final number consists of two parts which should be independently random. Each part is
    // converted to a number with base 32 in order to minimize overall length of the final number,
    // but still keep it very random (14^32 different strings)
    var id = Math.abs(time + getNavigationTime() - reduceMiscSessionMetrics()).toString(32);
    id += random().toString(32);
    return id;
