The time from the sun’s highest position one day until the next day’s highest position is 24 hours.
The period from the moon’s highest position one day until the next day’s highest position is 24 hours 50 minutes and 28 seconds.
A tide clock’s day and night accordingly lasts 50 minutes and 28 seconds longer than a normal day and night.
So the tide clock’s hand will use 12 hours 25 minutes and 14 seconds making one round, whereby the hand is showing precisely the cyclus of the tide.
