If an object were undergoing acceleration in hypothetical flat space, then a distant clock's tick rate (relative to one's own) is given by something like (1+gx)/gamma, where g is the acceleration and x (sign significant) is the significant linear distance to the remote clock. Is this part and parcel of the fact that SR can handle acceleration? Yes, of course it is. And if so, then is the formula above derived solely from the Lorentz transform? Just out of idle curiosity, how is that derivation arrived at?
