Brian timer not working

I’m trying to code a program that requires a way to keep time, preferably in milliseconds. And when i use the:


and print it to the screen of the V5 it says its 0, and when i use the


it prints a number in the millions (858,993,459 to be exact). So i might be using the command wrong or the brain’s timer could be off, but i doubt that. So is there any other way to make a timer/ make the brain timer work?

Make sure to have a reset timer, and start/stop timer
As in start/stop and reset the timer, not separate timers lol
