1. In Alan Lightman's book "Great Ideas in Physics" (Page 126?) he

frame corresponds to the passage of less than a clock second in the
observed B frame. This means that a clock second is not an interval of
universal time (absolute time).
No!
Seto, listen carefully--Each observer's own clock reads *proper time*
and measuring the clocks in other inertial frames having relative motion
is accurately predicted by special relativity. This is true for any and
all inertial observers.
Nobody is privileged or special!
