You need to define “move through time”. The only way to measure time is with a clock, and the clock’s motion relative to you affects the measurement.
If you let everyone define “time” as the thing measured by the watch on their wrist, then everyone moves through time at one second per second, but since people are in motion relative to each other and therefore have different frames of reference, their clocks will measure different times.
Since no frame of reference is privileged, there is no “absolute time”. Of course you could pick one and measure every event against that one, but that would be an arbitrary choice.
This is my understanding. If I’m wrong, I’d be happy to be corrected.
That's my understanding too but I am also saying that "less you move in time" needs to be more rigorously defined. As it stands above I'm not sure it makes sense, even though it might be a useful fiction to get a handle on the weirdness of it all.
