More reliable when we use setInterval to perform some timing tasks

I tested this on Mac OS X 10.14 with FF Nightly 70.0a1(2019-07-21) and here is my result from the console.
I'm not sure what should I see here and what is the problem in your case.

If the first print 1563974514669
 
I hope the 100th print 1563974514669 + 1000*10 + delay
Instead of 1563974514669 + (1000 + delay)*10

But the practicality is not high, you can close this bug
