Its part of the Lorentz transforms .. relativity of synchronicity (ie changes in clock sync when inertial frame changes) accounts for that. See the many example of the regular twin paradox from the point of view of the travelling twin for examples of how this works (the travelling twins measures the stay-at-home twin as aging faster during the turnaround). This is all well-documented stuff.
