The what now? Leap years are defined by the Gregorian Calendar, as
declared in the 16th century, long before K&R.
https://en.wikipedia.org/wiki/Gregorian_calendar
The rule for leap years is:
Every year that is exactly divisible by four is a leap year, except
for years that are exactly divisible by 100, but these centurial years
are leap years if they are exactly divisible by 400. For example, the
years 1700, 1800, and 1900 are not leap years, but the year 2000 is.
— United States Naval Observatory[2]
I don't have my copy of K&R close to hand, but my preferred implementation
for a function that decides leap years is (pseudo-code):
bool isleapyear (int year) {
if (year % 400 == 0) return true;
if (year % 100 == 0) return false;
if (year % 4 == 0) return true;
return false;
}
Why would you expect a time zone database to acknowledge one
implementation of a simple Gregorian leap year function?
