Todays question sent in by Vishal
In the good old days of mechanical clocks on ships, the sailors needed to have a very accurate timekeeper to be able to determine their longitude when at sea. When the ship was about to leave the shore, the guys on land would do something so that the guys on the ship could set their clock to be accurate as they leave the shore. With the advent of more sophisticated clocks, this tradition understandably went obsolete. However, this is still practiced as a ritual though for a different reason.
What would the guys on shore do to help the sailors set their clock accurately? And how is this tradition famous today?
Went uncracked
