The caravans that that were passing through Babylon could be helped by the astronomers by telling them the time of day it was and even the hour.

Explanation:

Many caravans passed through Babylon to buy goods from the merchants there. They would buy numerous items and trade things for gold and silver. This made Babylon very rich. The astronomers that were there believed their  Gods showed them the way by changes in the sky. They invented the Sundial and were the first people to use a calendar for the 7 day week.
