May I take this opportunity to wish all my readers the Season's Greetings.
This blog describes the use of time units on the Centauran Colony world of Osmum around Alpha Centaurus B.
The planet Osmum rotates once every 23 Earth hours. This is called a Dem.
The planet circles its star once in 262 Dem. This is called a Seas.
One Dem is made up of 20 Hue.
One Hue is made up of 50 Meg.
One Meg is made up of 100 Sum.
Therefore, one Sum equals 0.828 seconds, one Meg equals 1.380 minutes, one Hue equals 1.150 hours, and 224 light-Seas equals about 154 light-years.
I hope that this explains some of the terms used in the story.
Incidentally, there are four more Chapters to this tale. I do hope you like the ending. My Editor hated it, or rather me. I am not sure which.
