We should not that "time is ticking off more slowly" is not defined. All we we observe is that the rates of the clocks differ. The clocks tick slower or faster. We can of course define time to mean "rate of ticking of clocks" but then it is simply an abbreviation. There is no intrinsic physical meaning other than clock rates that run faster or slower.

This comes down to some semantics here. The clocks ARE all ticking off time at the same rate: just put the all the clocks stationary next to each other. However, observers will observe the clocks ticking at different rates if the clocks are moving at different speeds with respect to the observer. And different observers will also observe different rates with respect to other observers if they are moving relative to those other observers. A single clock can have many different rates simultaneously if many different observers moving at different speeds are observing that clock. All observers will observe the same rate of ticking of clocks that are stationary to them and that rate is the same rate as any other set of clocks that are stationary to any other observer. In this sense there IS a universal time: the rate of "my" clock (a clock stationary to me) has exactly the same as the rate of "your" clock (a clock stationary to you).

Food=time. More food=slower time. Fasting=faster time.

Does this affect still affect computer clocks?

All of this person's comments spew falsehoods. There's a reason they're taking the course and not teaching it. Whether they're allowing themselves to learn anything is another story.
