SR/GR use absolute time to synchronize the GPS clocks with the ground
clock as follows:
1. A standard clock second is defined to have 9,192,631,770 periods of
Cs 133 radiation or N periods of Cs 133 radiation.
2. Before a GPS clock is launched into orbit its clock second is
redefined to have (N +4.15) periods of Cs 133 radiation. This means
that while in orbit a GPS second is defined to have (N+4.15) periods
of Cs 133 radiation.
3. The reason for the redefinition of the GPS second is to make (N
+4.15) periods of Cs 133 radiation at the GPS orbiting location to
contain the same amount of absolute time as N periods of Cs 133
radiation on the ground clock.
4. The redefined GPS second makes the GPS clock in synch with the
ground clock continuously. The only daily adjustment is to correct the
daily drifts.

that's the current definition of the second.

You mean the clocks divider has to be modified to compensate for
relativistic effects.

No such thing as absolute time. If there was it wouldn't be necessary
to modify the clock.

sort of.

You have been totally mislead about this concept of "absolute"
time, distance, or position. Special and general relatively
have no need of absolute time and onservation shows that there
is no absolute time.

Seto--You really need to sit down and learn special relativity.
There has never been an observation that contracts a prediction
of special relativity. It remains a very fruitful theory and
you should take the time to learn it, Seto.

You are the only one who thinks this, Ken.

Synchronizing in two time rates is important. Equal gravity slow of
time for two clocks should be combined with equal energy flow through
space or equal pre speed.

When both rates of gravity and motion are synchronized by bringing the
clocks together then they will be in perfect synch. There are two
slowdowns of time rates in the universe; motion and gravity strength.
