60 is by far too low at this point of the game for large nations played by adult men with families and weekly schedules.
You didnt only take over the game where you didnt have admin role what so ever from the beginning, but now you try to manipulate who can play and who cant based on their free time.
This is not how the game should run, and I remember we having the same problem earlier in a different game where you had tendency to force host the turns (discussion of the problem starting from the page linked here):

The game schedule shouldnt follow THE FASTEST LEADING PLAYER, it should follow the reasonably slowest leading player which, it seems, would be in this case Timpaman (as no other big nations brought up the schedule problem), and the logical raise in the interval would be 24H at least, maybe not more thought.
If you have problem with serving the needs of the slowest players, maybe you should just stick hosting the games you start and hand over the admind back to me. Not saying you were not doing great job so far, and every1, especially me is greatful you took the initiative and solved the delay lock when I was busy with my IRL, but I need to underline here that this isnt a rush game as a whole - not anymore when its getting late and the stroms are gathering.
...just to make sure, we should let Timpaman decide what kind of interval he needs, if its only reasonable. So I am not saying we should get 72 just for the sake of it, but based on experience I would say raising the interval only little, like 12H, might very well significantly increase the need for extensions, which is less tempting than having a fixed schedule.
I also want to point out that in any case 60H interval for a long game on a relatively large map is just not enough to finish the whole game with. We should raise the interval in any case beoynd 60H at some point so why not serve the needs of the busiest players right away.
