Tide is the effect of the gravitational attraction of the moon, and in a lesser degree of the sun, on the waters of the earth, by which they tend to become heaped up at the point below the moon, and at the opposite point to this, so that twice in each lunar day there is an alternate inflow and outflow on the shores, modified by local configurations.
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.
The tide clock shows the flux and reflux of the tides. A tide clock showing "12 o'clock" means high-tide, and "6 o'clock" low-tide. The period from low-tide at "6 o'clock" till high tide at "12 o'clock" is called the flux, uptide or tide on the flow. The tide clock shows how much time has gone since last ebb, and how long till next high-tide. In the same way the period from high-tide at "12 o'clock" till low tide at "6 o'clock" is called the reflux, ebb or receding tide. There the tide clock will show how long ago the tide was up and how long before it will have receded.
At full moon and new moon the effect of the gravitational atraction of the moon and sun becomes reinforced, and an especially big tide-wave, the so-called tidal bore can arise.
The force of tidal waters can vary considerably, all depending on where the shore in question may be. So the tide clock must always be set according to the nature of the local tide. Once your tide clock is set, it will show your local tide correctly and permanently.
On the Delite tide clocks the short hand is the hour-hand and the longer hand is the "second"-hand.
The "second"-hand makes a round in approx. 64 seconds!
