Approximate. Phases come from a standard short series for the Sun and Moon built on the 29.53-day synodic cycle — good to a few minutes for the phase times, close enough for planning a walk, not for pointing a telescope. Times are your device's local clock. The drawn disc even shrinks and grows with the real distance.
