      • yearForCalendar

        private static int yearForCalendar​(int year)
        Returns a year within the range -999,999,999..999,999,999 for the given year. Too large and too small years are replaced with years within the range using the 400 years period of the Gregorian calendar. Because we need them only to calculate a time zone offset, it's safe to normalize them to such range.
        Parameters:
        year - the year
        Returns:
        the specified year or the replacement year within the range
