I've heard that Einstein wrote a paper in 1907 (2 years after his SR paper, and 8 years before his GR paper) that may have discussed the above result. I'm currently trying to find that 1907 paper (translated into English, of course). I'd like to know if he used CMIF (co-moving inertial frame) simultaneity in getting his result, and whether he made any assumptions in justifying that choice.
That is a quote from one of MY posts, not from aujlaakaran0, so I don't know what's going on here. I DID find a copy of that 1907 Einstein publication, and have read the part about clocks in the front and rear of a rocket, but I haven't been able to understand it very well. He doesn't appear to be assuming that an accelerating observer always agrees with the perpetually-inertial observer who is momentarily co-located and stationary wrt to himself. But Einstein also is doing the analysis only for an arbitrarily small acceleration.
