Chronosys - Terr Defined

The duration of a day is the time it takes for the Earth to complete one rotation on its axis. A Terr is defined as 1° of rotation of the cycle. Thus there are 360 Terrs in one day. Terr is pronounced like the verb tear, as in to tear a piece of paper.

The daily cycle defines our pattern of waking and sleeping.

Terr zero occurs at daybreak at the current location, which is defined to correspond to 06:00:00 hours in the old time system.

The Terr (time) at a given location depends on the longitude of that location. There are no time zones in Chronosys. Correlation of moments of time between two locations requires one to take the difference in the longitudes of the two locations. If the location you are referencing is to the east, then subtract the difference from the current Terr at your location to get the current Terr at the location you are referencing. If it is to the west, then add the difference. These two moments in time are the same from a global frame of reference.

The apparent length of a day varies throughout the solar cycle due to astronomical effects. The Terr is a measure of apparent day length, the same as would be observed on a sundial. Thus a Terr may have a different duration from one day to the next. The differences cancel out over the course of the solar cycle for a net gain/loss of zero.

Mechanical measurements of time are out of harmony with natural cycles, and therefore are not used in Chronosys. However, they may have some application in scientific measurements when the quotidian and solar frames of reference do not apply.
