This is mostly correct. Around each star is a habitable zone in which the star provides enough heat to sustain life to a planet. To close to the sun and everything burns, to far away and everything freezes.

So all planets sustaining life would probably have approximately the same orbit and approximately the same length year, in a standardized measurement system such as seconds, minutes, or hours.

Assuming all suns are the same strength, and all atmospheres are the same in density.

Yes, but not every star has the same strength, a younger sun might expand its life belt further than an older star. I think.

Yes a star's density, luminosity, and therefore energy output varies from star to star especially in the cases of newly formed stars and of older red giants. Hence why i used the word "approximately" in my previous post.

Even so there is a limit to a star energy output and therefore there is a habitable zone region around each star is (probably) somewhere around 1 earth year plus or minus a year or two( just guessing on the error approximation) This isn't that large of a zone when looking at the scope of the universe.

The earth's year is around 8800 hours and mars' year is around twice this and it still falls in the habitable zone.

Perhaps, the council/and or other races when determining a galactic year averaged the majority of life sustaining planets year length and it came out to around one earth year.

Of course much of the argument is a moot point as much of a planet's temperature relies on its atmospheric conditions as well as its distance from the sun.

Just saw your post and mostly touched on this already.

To be specific:



"The galactic standard year is the equivalent of 1.043 Earth years." From the Galactic Codex: Essentials I got from the ME LCE I got.



Examples:

Rachni Wars: 0-100 AD/CE for us, 480-575 GS for them

Krogan Rebellions: 700-800 for us, 1150-1246 for them



Year in ME: 2183 AD/CE or 2572 GS

A Galactic Standard Day is comprised of 20 hours.



Each Hour is comprised 100 minutes.



Each Minute is comprised of 100 seconds.



Each second is half as long as a human second.

From Mass Effect Revelation:

[Most planets] orbits all fell in the narrow range known as the life-zone: too close to the sun and water would exist only as a gas, too far away and it would be permanently trapped in frozen form. Because of this, the time it took the home world of almost every major species to complete one orbit around its sun varied by only a few weeks. The galactic standard year—an average of the asari, salarian, and turian years—was only 1.09 times longer than Earth’s.

Shepard: Be here in an hour Wrex

Wrex: okay. . .

- one galactic standard hour later -

Shepard: What the hell Wrex, you're 40 minutes late!

More like the other way round. Stars tend to brighten and swell as they age, even when they're still in the main sequence.

Time references notwithstanding, it's the weird references to age that's got me really put off. I can understand how an asari might be negotiated with to with a turian to establish timelines more conducive to trade. But I don't get how they'd agree to a time system that didn't have easy ways to measure long periods of time.



To an asari, a thousands years isn't that long, because most of the race lives to be that age. Since they live to be 10 centuries, they should measure age in decades, the way we measure it in years. No one says, "I'm 5000 days old." It's too inconvenient. In the same way, even with a standardized year system, an asari like Liara should say something like "I'm only 10 - that's young for an asari," somewhat missing the necessary reference that she's talking decades, not years.

[insaneqwert]

Even assuming that Asari and Salarians both happened upon the base-10 number system and chose it by chance, the problem of where a "second" comes from still arises.

[from wikipedia] second: the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.

read: due to the entropy of the universe and all that, humanity has decided to use a (more) exact measurement roughly equivalent to the "old" second based on day/night cycles. I haven't read Revelation, but having a galactic standard (GS) second being defined as being half a "human second" seems rather absurd considering the arbitrarity with which we [humans] have decided to define a second. Although its most likely due to the logistics of having alien races, it would be good to have a codex entry in ME 3 to make sense of the issue.

Considering the shortness of Salarian lifespans it would make sense that Asari and Salarians would strike a compromise somewhere in the middle for units of time, although its rather incredible that the system even remotely resembles Earth units of time.
