Titan Meridian Time

Overview

Titan Meridian Time is the measure of time passed since midnight on the prime meridian of Titan, moon of Saturn. It features a 24-hour clock similar to the one used on Earth, though marginally shorter. Titan solar days are about 16 times longer than Earth days, so each day is further broken up into 16 'circads' which act as days.

Titan is tidally locked with Saturn, meaning one side of the moon always faces the planet and the other side always faces away. The prime meridian is determined to be the meridian on the moon's surface that is facing directly at Saturn.

Midnight is thus the time when the moon is directly between Saturn and the sun, though this is only used as an epoch for the beginning of the first circad in each solar day.

Titan Meridian Time is a name that was chosen for this website and might not be accurate.

Info

As the orbit of Titan is not very inclined, midnight on Circad 1 is also roughly the time of a total solar eclipse on Saturn.

Accuracy

The accuracy of this timekeeping system is wholely dependent on the writings and calculations of Thomas Gangale. It is likely that these calculations weren't precise enough to extend more than a few decades, as they do seem to drift from ephemeris data.

It is unknown if this calculation takes the time it takes light to travel from Saturn into account.

The name of this timekeeping system is my own creation, as Mr. Gangale did not give it a name himself.

It can be somewhat calibrated using this model if you know what you're doing.
