t' = 1.00000000067315⋅t second - 48.96 ns

or 48.89 ns, doesn't matter, this is not the problem

The point is that this can be written:
t' = (1 + 0.673e-9)t - 48.96 ns
If t = 100, we get
t' = 100 seconds + 67.3 ns - 48.96 ns = t + 18.34 ns

You can't set
t' = (1 + 0.673e-9)t - 48.89 ns ≈ t - 48.89 ns

unless t is _very_ small.
