731 = 365 + 366, the number of days between 1.1.1978 and 1.1.1976. Using 1976 makes working out leap years simpler. 1461 = The number of days in four years including 1 leap year. (eg 365*3 + 366) 86400 = The number of seconds in one day.
I used these as constants so that they don't have to be computed on the fly, or read from variables.
Renamed utility_intern.h to intern.h.
