Units and Measurement in the Empire of Humanity - Time

Basic
Imperial measure owes nothing to any Earth system of measurement. The Imperial system was designed in an already scientific and technological era for much the same reasons Earth's metric units were designed - to simplify a complex system of historical measures.

The numeration system is base sixty - 3 times 4 times 5. This makes numbers more easily manipulated than previous systems. It works upon the same positional basis as our Hindu-Arabic system, and the same concepts apply, with multiples of 2, 3, 4, 5 and 6 (and 10, 12, 15, 20 and 30) having intermediate importance in thought between the unit and the system base of sixty. For all units, the digital places are described thus:

Prime: 60 times the base unit
Square: 3600 times the base unit
Cube: 216,000 times the base unit
Fourth: 12,960,000 times the base unit, and so on.

For fractional numbers, iprime is 1/60th of the base unit, isquare is 1/3600th, ithird is 1/216,000th, ifourth is 1/12,960,000th, and so on. If there's an 'i' in front of the multiplier, it relates to a fractional number.

For situations requiring more precision than a single digit, the spoken convention is to specify the magnitude of the leading digit, and following digits are presumed to be immediately decreasing in magnitude. "Two minutes thirty" can be two and a half minutes of time, or two and a half light-minutes of distance. "Seven ithirds fortysix fourteen" would be seven 216,000ths, forty-six 12,960,000ths, fourteen 777,600,000ths of the relevant units. If the relevant digit is a zero, the zero is spoken, so "seven ithirds zero fourteen" would be seven 216,000ths, zero 12,960,000ths, fourteen 777,600,000ths of the relevant units

Most of the time, measures are context sensitive in translations to English. For instance, a range is assumed to be given in distance units, a mass or weight in terms of mass units, and so on. In Technical, the fact of what you are measuring requires the units of measurement to match, and this has, over time, leaked over to conversations in Traditional as well. In Mindlord, everything is context sensitive anyway, and nobody uses Concept for technical or technological purposes, as the 'language' is entirely unsuitable for that purpose.

Time

Imperial time units are recognizable to Earth. They have seconds, minutes, hours, etcetera. The one irregularity is that a week is sixty hours separated into four fifteen hour days. A year is sixty weeks, intermediate 'months' of four, five, and six weeks are also used but not formally encoded or legally enforced unless formally encoded as such in a contract or memorandum of understanding. The 'standard' Imperial workweek is fifteen hours, but few people adhere to such regularly and almost nobody with any sense of legal rigor. Work arrangements are typically individual between employer or contractor and their employee or sub-contractor.

The basis of the system is the second, all other units being defined in relation to that.

1 Imperial second = 1.7 Earth seconds
60 seconds = 1 minute = 1 m 42s Earth time
60 minutes = 1 hour = 1hour 42m Earth time
15 hours =1 day = 25.5 hours of Earth time
60 hours = 4 days = 1 week = 102 hours, or 4.25 days of Earth time
4, 5, or 6 weeks = 1 month
60 weeks = 1 year = 6120 hours, 255 days, or .698 years of Earth time
60 years = 1 prime = 41.89 years of Earth time
3600 years = 1 square = 2513 years of Earth time
216,000 years = 1 cube = 150,800 years of Earth time

1 earth year = 1.432 imperial years

1 earth century = 143.2 Imperial years (spoken as "Two prime twentythree point twelve" i.e. two sixties, twentythree units, twelve sixtieths)
