    So far, you are closest to the truth, but it it is still not correct. Given that
    you are using the heavy battery, you should be within the second.
    
    Hey, Zorbec, Garry, et al.! Instead of getting so worked up over this, how about
    reading what we discussed here on the list last equinox? (And probably every
    single equinox before.) Equinox is NOT when the declination of the sun is zero,
    but when its ecliptic longitude is zero.
