If it was the case, then some interesting emergent gameplay could happen. 
 
For example blueprints and components to do with lighting would be more valuable on a planet with very short days, than a planet with very long days. Which would create trade routes, actual supply and demand markets, etc.

Hi everyone.
 
We have already a game vision. But we are also aware it can always be perfectible.
And for that, we need you: Help us improve the game in order to make the next best Sci-Fi MMORPG!

Our planet Mercury has an extremely long day. It takes so long for the sun's light to get all the way around the planet that Mercury was once believed to be tidelocked.
 
As per your question/suggestion regarding the game, we can't know for sure until we know exactly how planets will end up working in the game. Depends on if they're completely fixed, if they're fixed in space but rotate about an axis, or if they orbit the sun and rotate about an axis. However, no matter what, I would imagine that day length in DU would change with the solar system.

I think large Orgs will be able to decide for themselves how the land is distributed or used.  But it's been said before, it's possible to play this game solo so we would probably be able to trade for a TU eventually.  The issue will be getting the prime locations, which will take time to establish themselves.
