Solar Year (SOL) & Time

The use of Sol's time systems for a 24 hour day and the Gregorian calendar evolved from the need for a centralized mechanism to demarcate time. Strangely enough very few alternatives were explored before the age-old simplicity of the Earth-based system was adopted for early space colonization.

Solar Year (Sol)

The Solar Year (SOL), is a calendar based around the time-frame of Earth's transit around its Sun. Unlike the calendar of old, the solar year is not broken by seasonal months. Instead the calendar is simply a time frame, a predetermined interval which people and computer systems are able to gauge accurately. Despite this many locations still reference the Earth months on principle that it gives the numeric date a recognizable reference point.

A computer sees this time as yet another definition. A year is 365 days, those days are 525 948.766 minutes, and those minutes are just the same as 31,556,926 seconds. Simple, really.

Time

Just as dates are artificial intervals no longer tied to the passing of solar bodies, time has remained standardized along the Earth-based Greenwich Mean Time (GMT). The 24-hour clock exists in all locations and ticks with one heart, carried on the currents of the Tachyon Data Network
