This guy will probably die before that mission gets done.

Haha, that's a rather interesting issue as the game relates to real time and not in-game time.

Should be cheatable then, I didn't try it though, didn't know this till yesterday in fact and I've finished the game.
If I knew, I'd try to cheat "the axe" mission that lasts 24 hours. If I ever replay it, I'll definetly try with system time change for this superlong mission.

I just did that one with my 2nd character, and it's really not that bad once you're aware it. Last time it pretty much hit me out of nowhere though, and it was hard to lock down one of my agents for so long, but this time I knew it was coming and simply triggered it at a time where I knew I wouldn't need the agent in question for some time (basically pre-Skyhold, because Skyhold unlocks a ton of missions).

I honestly feel some of the missions are a bit too long, but I guess the reward from that particular one is worth it. The staff is very, very good early on.
