I suspected as much. I cant think of any reason why ancient
societies would need to measure time to smaller units than a
second. So if a nimesa is longer than a second, then a yojana
is longer than 42 miles, also an improbably long unit for an
ancient society.

Could they not measure the time that Io was eclipsed by
the planet, then assume this equal to the time required to
cross in front of Jupiter, then work out a means knowing
the light is delayed more on the far side than the near
side? Given good telescopes and watcher, seems like
one could estimate c with that info. spike
