There is an article in the 24 October issue of PHYSICAL REVIEW LETTERS
(Vol. 51, p. 1501) by Cohen, Moses and Rosenblum on

"Clock-Transport Synchronization in Noninertial Frames and Gravitational Fields"

"It is shown that electromagnetic and clock-transport synchronization
procedures are not necessarily equivalent.  In noninertial frames and in
gravitational fields both procedures can be path dependent.  Even for the
same path ~100 km above the Earth, the two procedures can give different
errors, ~89 usec/day (clock-transport synchronization) and ~60 usec/day
(electromagnetic synchronization)."
