How accurate are these celestial event times?

Every event is computed with the Swiss Ephemeris (DE441) and resolved to the millisecond. The engine is verified against NASA JPL HORIZONS - The model that flies spacecraft - On the 2026 major events. Almanacs stop at the minute. Starmap does not. Far-future instants ride the projected Earth-rotation model and may drift by seconds (up to about a minute by 2099) as observations land.
