I doubt the universe works like that. Not even computers work like that. It is an abstraction added artificially to some games like Minecraft. Processers has multiple cores with multiple threads, all working independently of each other and with a speed depending on hardware. And uses a ton of shortcuts, to be faster, that breaks that structure like jumping threads.
The shortest amount of time that is not 'no time', is planck time, which is the time it takes light (the fastest possible movement), to travel the shortest known distance, a planck length.
