I am obviously doing something stupid...
Why are my sunrise and sunset messed up? I have adjusted the time zone (-6). I even tried to set it to zero and it is still not correct. I am assuming that the numbers below are times on the clock, not some other calculation.
$Time_Sunrise: 16:24  $Time_Sunrise_Twilight: 15:51
$Time_Sunset: 5:44  $Time_Sunset_Twilight: 6:18
