(To connect to the topic again)
If I say that "some number of seconds after an epoch" is a well defined point
in time, then I�m definitely telling nonsense from the view of spacetime
physics. So I have to make the restriction that "good old theories" are
sufficiently applicable (no "pop culture" here :-)). These restrictions include
high speeds and different gravitation.
