Interstellar Standard Time (IST)
Interstellar Standard Time
Interstellar Standard Time was developed in the late 21st Century as humanity was venturing further and further out into space. Initially known as Zulu Time, also known as Greenwich Mean Time (GMT), it was then called Tranquility Mean Time, when the US Astronomical Survey established a base there at Mare Tranquility, next to where Apollo 11 landed, and established a new Mission Control for further missions to Mars and beyond. In 2092, the UN Treaty of Space established the Interspace Standard Time, which, on January 18, 2127, was renamed to Interstellar Standard Time as soon as the first unmanned mission to Proxima Centauri successfully returned in order to commemorate the event. It is considered the international standard of time measurement, even as others use a Metric Time Measurement.
According to the International Standards Organization, published as ISO 600281, the current arrangement of temporal annotation by most systems arranges it with seven digits for the year, the month, and the day, each with a two digit notation. The year always uses the last two years of the present Gregorian year; the month is always annotated with two digits of the present month, for example February would be noted as 02; the day as a two digit day. It would then be followed with a colon, followed by the time by 24 hour standard notation.
Example: 10:30 PM February 6, 2771 would be listed as (7)710206:2230. Often times, most people leave out the first digit in parentheses.
