Which outcome reliably enables accurate timekeeping using astrolabes?

💡 Explanation

High altitude astrometry achieves precise timekeeping because angular measurement enables pinpointing celestial altitudes relative to coordinate system altitudes, therefore allowing calculation of local time, rather than relying only inaccurate ecliptic shifts.
