Question about Turn Timer in pitboss

[45°38'N-13°47'E]

Can someone enlighten me on how it works?
If I set a turn timer, for example 1 hour, what happens if a player doesn't take its turn? Does it just skip to the next turn or without doing anything?
Also the tooltip in the mp interface says that it's scaled based on the largest civ: what does it mean and how is it scaled? I mean, if I set a 1 hour timer does it actually get longer further in the game if my civ grows? Is there somewhere where I can control the scaling in this case? Thanks.

Yes, when the timer ends, the turn ends and is processed. I'm not sure if automated units get processed, but I suspect they might.
I'm not sure how the scaling works, but on Ramk's servers at least 20 hours ingame is 24 hours realtime.

Scaling: This tooltip info targeting normal MP games. In normal MP is the turn timer not a constant value but respects the size of the empire to handle.
In Pitboss games the timer is constant for the whole game (unless you use the additional functionality from the pbmod).

If a player skip its turn the automated tasks, e.g. worker tasks, will be handled. This is similar to single player games where you hit the end turn button.
