A new result is proposed for the time dilation effect of the round trip, known as the twin experiment. This differential ageing effect has strangely been treated in general relativity in absence of gravity and in special relativity in absence of uniform motion, which misleadingly inspired the idea of paradox. The alternative Doppler treatment proposed here reveals a new solution unrelated to the Lorentz dilation factor. This solution is then shown consistent with the general time-energy relationship which applies to all cases of time distortion, including special relativity, gravity and cosmological expansion.
