You don't need to buy an absolute clock. All clocks measure absolute time
except that the amount of absolute time they measure for a clock second is
different in different frames. An observer can define his clock second to
measure absolute time then he can use the LT or the Doppler Transformation
to calculate the clock time value of his defined absolute second in the
observed frame. That's how the GPS system works.
