Performance of Date.now() vs (new Date).getTime()

172

var timeInMs = Date.now();

per MDN

vs.

var timeInMs = new Date(optional).getTime();

per MDN.

Is there any difference between the two, besides the syntax and the ability to set the Date (to not the current) via optional in the second version?
