Pandoran time-frame

[Eanikran]

I've been thinking about this for a while. A couple times in the movie, people are referring to times and deadlines as if they were on Earth, for example, Trudy says "we bounce at 09(00)". I'm wondering if a day on Pandora is 24 hours, which it probably isn't, so people wouldn't be able to go by the standard 24 hour clock. did they just adjust the number of hours to accommodate the number in a day?

Just a thought

To me, it'd make the most sense to adapt the number of hours in a day to the day/night cycle there.

Of course, this makes for issues when you try to compare it to 'Rrta time. If Pandora had a 36 hour day, 1 Pandoran year would be ~1.5 years on 'Rrta...

well, that's the thing, the number of hours in a day does nothing for the number of days in a year, the only way to find that out is to ask Eywa
you can't really tell where you are in orbit of Pandora's sun, so it would be pretty tough.

Oops...faulty logic...posting at 2am. Hours per day and days per year are indeed not related. One comes from the day/night cycle, and the other comes from time needed to orbit the sun once...

There's a LST (local solar time) clock in the video logs.

If it was really a 36 hour day, wouldn't the Na'vi get tired? Even if they did sleep for 18 hours of it.

The biology is different, so the sleeping needs are different.

There are some humans that only need four hours of sleep a night. It's all chemistry.

['Oma Tirea]

Even if the Pandoran day isn't some 36 hours there are at least some time boundaries set to it....

the LST clock shows the equivalent time on Earth - a day on Pandora could be longer or shorter than on Earth (with the size of Polyphemus, likely longer in both daylight and nighttime), in which case then the date displayed would probably be adjusted for the differing day length.

I was thinking about this:
since Pandora is a moon, and not a planet, and it orbits Polyphemus, it's nights and days would be really offset and askew. Assuming Pandora rotates as it orbits Polyphemus, which orbits the sun (can't remember which AC it is), you'd think Pandoran nights/days would always be different lengths, from either being on the side facing away from the sun, or when it's in Polyphemus's shadow.

Time of day I can't help with, but remember Jake's first experience of driving his avatar?
It ends with him 'going to sleep' in a bed in the avatar bunk room. There are mosquito nets around it, there's something that bites (Selfridge calls the Na'vi "fly bitten savages") so biting flies.
But the nets are open, so no attacks that night. Therefore, logically, there must be a season in which they will bite, and one where they won't.
From Jake's arrival on pandora to the end of the movie is ninety seven days, during which we don't see any one swatting at insects in a frantic way, so the non biting season must be at least that long.

OK, this is a big step from an open mosquito net and one off-hand remark, and yes there could be other explanations, but.

Clever. I would never have thought of that.
