Its the half the time of the round trip, by definition. That's a main part of the paper..allowing this second clock be synchronized.Mister T said:The first clock-reading is ##t_1##. The second clock-reading is ##t_2##. The elapsed time between them is ##\Delta t=t_2-t_1##. You need two clock-readings to establish an elapsed time ##\Delta t##.

There is no absolute time in relativity.JAYJACOBUS said:Don't all clocks exist at the same absolute time
I've no idea what a "relational" speed is. Do you mean a relative speed? If so, then speed relative to what?JAYJACOBUS said:but move at different relational speeds?

it can synchronize the first clock too...Mister T said:There's no second clock involved in the point I was making. One clock, two readings taken on that clock. Their difference is an elapsed time, and that's something that requires a standard to be able to measure.
On the other hand, synchronizing two spatially separated clocks requires nothing of the kind, just a convention.
