I submitted this in revision 17905. This counts time you have adventured in the Gingerbread City in _gingerbreadCityTurns. I wasn't completely happy because it doesn't count turns, per se: the noon and midnight NCs do not take turns, but are counted anyway. However, upon further reflection, I think this is correct: unless we count the NCs, if that property is 9, have you or have you not gotten the noon NC yet? As is now, if 9, noon is next, if 10, noon is done.
Setting _gingerbreadClockAdvanced is true if you have advanced the clock. So, that was done on turn 1, turns 2-4 are adventures, and turn 5 will be noon.
I can work with that.
