  No they won't. Sync only occurs if the observers are geosynchronous to one 
another. In other words if the observers and their clocks are apparently 
stopped relative to one another. If the two are closing distance between 
them, no matter what the velocity, each will see the other's frequency of 
ticks of a second on their clock to be closer together than their own 
clock's frequency of ticks of a second. The faster the closing the closer 
together the frequency of ticks on the other clock versus their own clock's 
frequency. Relativity's [rubber band] of space-time between them will be 
contracting in its elasticity, not stretching out (Relativity's balloon of 
space-time between them will be deflating rather than inflating).

  If the two are opening distance between them, no matter what the velocity, 
each will see the other's frequency of ticks of a second on their clock to 
be farther apart than their own clock's frequency of ticks. The faster the 
opening the farther apart the frequency of ticks on the other clock versus 
their own clock's frequency. Relativity's [rubber band] of space-time 
between them will be stretching out in its elasticity, not contracting 
(Relativity's balloon of space-time between them will be inflating rather 
than deflating).

  The reality of each observer and each clock will be hidden in the 
unobservable universe. There will be [light-time] space-time distance 
between them putting each of them light-time in the past of the other 
regarding any and all observation. Each reality of observer and clock hidden 
away from any possible observation of truth of 'there and now' by the other 
observer at 'here and now'. They will have no instantaneous communication 
with one another, nor any instantaneous observation of one another. Each, to 
the other, will be an observed virtual reality in the "observed universe," a 
space-time frame that can never be totally in sync -- regarding either space 
or time -- with any observer's own immediate space and time frame.

  You or anyone else can insist all they want that they aren't dealing in 
any virtual realities, but are only dealing in the reals. And I will tell 
you science is based on observation and observers rather than perception and 
perceivers of simultaneous -- UNOBSERVABLE -- realities. The scientist needs 
to be aware of the mutual co-existence of these particular two opposing 
universes that aren't just possible universes off in some hyperspace-time 
but are always starkly right with us everywhere in everything around and 
about us. Very confusingly so. Even the very best of physicists, the highest 
geniuses of physics, tend to forget about both the existence of and the 
literal immediacy of the unobserved universe (the unobservable universe). 
And in that tendency forget that the unobservable universe, therefore the 
unobservable traveler and clock, is the ones forward in time -- to now (the 
"observable universe," therefore the observable traveler, or the observable 
observer, and "other clock," always the ones trailing behind in time to the 
unobservable). Right here and right now (wherever "right here and right now" 
are) is the only space and time they will ever come together and merge.
