you will notice that the timing section has undergone a few revisions. Originally I had thought that

Which used to make sense. Using the common denomimation that most people think that 1 micron is actually 0.6 Terran seconds, we then have a day that is shorter than an Earth day, but a yahren is significantly longer. Unfortunately, I do not think that that works anymore.

The centons to the centar and microns to the centon still hold (there's lots of evidence in the series to support this base ten attitude, along with a few quotes from "Take the Celestre"), but then it falls apart. I used to think that 10 centons were a day, and indeed a lot of people in their studies agreed, but looking at the "Fire in Space" and "Take the Celestre" again, we find that perhaps this is not so.

A work shift is 8 centars in length, and the people on the Celestre were pulling 16 centar double shifts. In "Fire in Space", we find that Boomer has a furlough of 24 centars, and he mentions it like a 'day off'. So, the evidence points to a day being 24 centars, which is very Earth like, which could be good or bad. Bad in that the writers were suddenly thinking like Terran humans, or good in that our Earth follows similiar conventions to Colonial times, and maybe a reason for why we use 24 hours per day now.

So, using this 24 centar day, we get a Colonial day to become exactly 40 Terran hours in length, which leads to several conclusions, one of which is that the Colonials have more stamina than Earth Humans because they generally use more of their day working and can pull double shifts without too much hassle over short periods of time.

Unfortunately, this is the only rigid part of the time system.
Trying to figure out the rest of the system was then difficult. Using a base ten system, you could get anything from 10 days to the week, 10 weeks to the month, and 10 months to the year making a yahren of some four and a half times an Earth year. So then I went back to the measurements and started looking at names, and the one that springs instantly to sight is 'quarton'. Which implies quarter. So we could then have 10 days to 1 secton, and 4 sectons to the sectar. Which still gives an overly long year when compared to an Earth one. However, the basis seemed right, and I wanted ten sectares to the yahren, so that meant playing around with the amount of days in the secton.

Which eventually got me down to 5 days a secton. This would make the yahren shorter in length than an Earth year by some 760 hours, or just over 1 month in length. At which point I thought, fair enough, fandom generally says that 1 yahren is actually only two thirds of an Earth year, so what the heck.

Fandom generally assigns this though, based on characters apparent ages and then assuming that the Colonial life span of 200 yahrens is equal to the modern life span of 120 years maximum. In my opinion, this is a bad judgement call. The Colonials are more advanced than we are currently, so better medicine and better knowledge could quite easily increase the life span of a person. This is especially true if you think that Galactica 80 actually happened, then you have a clear indication that Colonial medicine is far in advance of ours.

The other aspect of fandom uses 0.6 seconds to equal one micron, and this is based on the fact that 1 week equals 1 secton, and uses 100 microns to the centon, 100 centons to the centar. This system (as appearing on the Kobol site) seems to imply that 10 centars equals 1 day, 10 days to the secton, which unfortunaly either means that the quotes from "Fire in Space" or "Take the Celestre" are incorrect, or something else.

Blurring all of this, is indeed something else. It is taken for granted that all space ships use the same time, which would be logical. However this time would have had to come from somewhere, so either one of the Colonial planets has put its time scale over everyone else, or else there was another time scale already in existance. Maybe from Kobol? So, do planets use individual time scales - after all, they are orbiting three different suns in different orbital zones (one hopes!) - or do they all use one time scale and work to that? This would certainly support the fact that the term 'day' does not really have any use and that all time measurements are in centars instead. It would also make sense because based on what humans are like on Earth, people like to live during the day, and and rise and set with the sun, so if you colonised a new planet which was similiar to Earth, you would attempt to do the same, and over time would likely adjust to the new planet.

I have assumed that the Colonials use several different time scales, one per planet, with an overal standard time which is used for the military, space travel and events that need to be standardised over a large distance.

And thus we end up with the following timescale for Colonial Standard Time:
