How do I make a speedrun timer?

I'm working on a game and i want to add a speedrun timer with milliseconds, seconds, and minutes.

Precise timer example

Use a numeric variable for elapsed time

In a text object display :

minutes = zeropad(floor(ElapsedTime/60),2)

seconds = zeropad(int((ElapsedTime)%60),2)

milliseconds = mid(tokenat(str(ElapsedTime),1,"."),0,3)
