Local simultaneity conventions are mathematically represented by connectionson the bundle of timelike curves that defines the frame. Those simultaneityconventions having an holonomy proportional to the Riemann tensor have aspecial interest since they exhibit a good global behavior in the weak fieldlimit. By requiring that the simultaneity convention depends on the theacceleration, vorticity vector and the angle between them we are able torestrict considerably the allowed simultaneity conventions. In particular, wefocus our study on the simplest among the allowed conventions. It should bepreferred over Einstein's in flat spacetime and in general if the tidal forcebetween neighboring particles is weaker than the centrifugal force. It reducesto the Einstein convention if the vectorial product between the accelerationand the vorticity vector vanishes. We finally show how to use this conventionin practice.Comment: 19 pages, Revtex4. Some misprints removed. Final versio
