How is the speed of light accounted for in the definition of UTC?
In other words, how did they solve the conflict where on one hand we'd all
expect two perfect clocks to tick at the same time but wether they do
depends on the location of the observer?

00:00:00 UTC is the same time everywhere. propagation only affects it
if you are transmitting a signal based on UTC. If I send a signal at
00:00:00 UTC from LA to Greenwich,

Redondo Beach,
The question has both a frequency and a counter part, as does any
clock.
The frequency shift with gravity has been nicely addressed by tvb
and others.
The counter of the frequency is subject to phase shift caused by the
speed of light and the distance to the measured source. Each counter
must be
The counter of the frequency is subject to phase shift caused by the
speed of light and the distance to the measured source. Each counter
must be given an initial value of time in order to be called a clock.
Hi Bill,
When not in motion it's easy to synchronize remote clocks --
