Is "End of turn" and "End of discard phase" actually the same thing?

I'd like confirmation on this. I've seen older rulings that indicate this is the case, but it seems strange to me.

Is "End of turn" and "End of discard phase" actually the same thing? And therefore, does what happens at the end of the turn, for all practical purposes, occur within the discard phas

EDIT:Okay, I've been researching in old forums and I see that's the case. Using two different terms to refer to the same thing has led me to make a mistake.
