Setting the time to the values indicated only works if that time hasn't occurred yet. So, if there is a 0 in the days slot, it will never work b/c the game starts on day 1. But if the day is set to a time in the future, it will work.
I don't know that this helps that much though. Sorry about that.
I'm guess the way that this has to be done is though the logic block event. I don't know how, at the moment, but I'll poke around some.
