    If you can reliably aim your sextant at a point on the horizon that's due north or due south plus or minus a few degrees, within ten minutes of noon, and measure the angle between the Sun and that point, the angle that you get will stably match the noon altitude (or 180-that) for a convenient, extended period of time around local noon.

    This might apply equally well to time sights.  With the Sun near the zenith, and using a point on the horizon that's known to be nearly east or west, a time sight will be stable.

    Cheers,
    Peter
