Movement while under attack

[newbie4]

I'm a relative newbie, and I'm learning that there are various undocumented "features" of the game.

For example, Depot stations usually move resources around in 2 minutes.  But when under attack, it takes 10 minutes.

It also seems that building things take longer if you start them while you're under attack.

Are other things affected?  What about Relocating troops?  It normally takes 10 minutes.  Does it take more time when you're under attack?

Where is stuff like this documented?  It sucks learning about this all of the sudden when you're being attacked ... you expect to be able to move things in 2 minutes and the counter says 10 minutes and you're saying "holy shit! what's going on?!?"
