TwoDigitYearMax is the last year in the 100-year range that can be represented by a two-digit year. The century is determined by finding the sole occurrence of the two-digit year within that 100-year range. For example, if TwoDigitYearMax is set to 1429, the 100-year range is from 1330 to 1429; therefore, a 2-digit value of 30 is interpreted as 1330, while a 2-digit value of 29 is interpreted as 1429.
