A method for diffusing channel timing among a plurality of subscriber units operating in TDMA Direct Mode, wherein the method includes: receiving, from a second one of the subscriber units operating in the TDMA Direct Mode, a first message; determining first channel timing from the received message; determining whether the received first channel timing is correct, wherein the determining is based at least on comparing a generation of the first subscriber unit with a generation of the second subscriber unit; when the received first channel timing is correct, starting a random delay; upon expiration of the random delay, transmitting a first forced propagation message to propagate the first channel timing to at least a third one of the subscriber units operating in the TDMA Direct Mode and having a higher generation than the generations of the first and the second subscriber units.
