Comments, with reply, on ´Synchronization and relativity´ by G.M.R. Winkler

The commenter asserts that the above-titled paper by G.M.R. Winkler (see ibid., vol.79, no.7, p.1029-39, July 1991) perpetuates a fairly widespread fundamental error by using a semipopular explanation for the dissemination of time in rotating frames of reference. The misconception that one must employ general relativity to describe kinematic phenomena (synchronization, Sagnac effect, etc.) in accelerated systems, even in flat space-time, is exposed by the commenter, who proposes a way to resolve the problem. Winkler replies that he shares the commenter´s concerns but does not necessarily agree with the way he proposes to resolve the issues, and he presents arguments to support his position. In a further comment, the commenter disagrees and offers further discussion.<>
