# Are time and length independent or can one be derived from the other?

In particular, the time coordinate $$t$$ can be choosen so that the mathematical expression of the physical laws reflects their inherent symmetries. Already Newton's first law then fixes the time rate upto a constant multiplier (that is, up to a unit) to be such that equal spatial increments along a free path correspond to equal time increments. (Page-42, Rindler's Relativity)

I have two main questions from the above paragraph:

1. Does the above paragraph imply that time is a derived quantity from motion of a particle?

2. If the answer to above is yes, Suppose we have a body which is free of any force, and we are in a frame seeing it move at zero velocity. Does this mean time has stopped according to the above? Another observer would see it moving and hence say that time is flowing, but then this would lead to breaking the absolute time idea in Newtonian Mechanics
