Isn't this about time acceleration?

I just have to say that the atom-clock onboard spaceshuttles lags behind a few (mili)seconds. So those people allready made time go faster

Lightspeed = totally different effects of time.

But hey this makes me wonder. If time is slowed down, like when going with light speed... the movement of the atoms would objectively allso be different... yet temperatures do not really behave differnt when going with lightspeed? Or like... is it?
