UtSystem or Date() faster?

Rus

I need a simple clock to run in the background while the game is progressing.

I have the choice of using :
JavaScript's requestAnimationFrame() in conjunction with either :

• UtSystem.getUserTimeMSec() or
  
• JavaScript's Date().
  

I would like to ask: which is more efficient?
Thank you in advance

Hi, Rus .
FPS control in requestAnimationFrame I think difficult .
I think that JavaScript's Date () or SetTimeout () is good .

Ok thank you
