Given a century, - * x, the year is assumed to be within the range x - 80 to x + 19. The value - * itself is then used as a match against the two last digits of one of these - * years. For example, take x to be 2004. A two-digit year is assumed to fall - * within the range x - 80 (1924) and x + 19 (2023). Thus, any intepreted value - * between 0 and 23 is assumed to be 2000 to 2023 and values between 24 and 99 - * are taken as being 1924 to 1999. This only applies for the case of 2004. - * With a different year, the values will be interpreted differently. 2005 - * will used 0 to 24 as 2000 to 2024 and 25 to 99 as 1925 to 1999, for example. - * This behaviour differs from that of <code>SimpleDateFormat</code> and is - * time-dependent (a two-digit year will be interpreted differently depending - * on the time the code is run). - * </li> - * <li> - * Numbers followed by a colon are interpreted by first an hour, and then - * as a minute, once an hour has been found. - * </li> - * <li> - * <li> - * Numbers followed by a slash are regarded first as a month, and then as - * a day of the month once the month has been found. This follows the - * U.S. date format of mm/dd, rather than the European dd/mm. Months - * are converted to the recognised value - 1 before storage, in order - * to put the number within the range 0 to 11. - * </li> - * <li> - * Numbers followed by commas, whitespace, hyphens or the end of the string - * are interpreted in the following order: hour, minute, second, day of month. - * The first type not already recognised in the current string being parsed is - * assumed. - * </li> - * </ul> - * </p> - * <p> - * A sequence of consecutive alphabetic characters is recognised as a word, - * and interpreted as follows, in a case-insentive fashion: - * <ul> - * <li> - * The characters 'AM' or 'PM' restrict the hour value to a value between 0 - * and 12. In the latter case, 12 is added to the hour value before storage. - * </li> - * <li> - * Any words which match any prefix of one of the days of the week ('Monday', - * 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday' and 'Sunday'), - * are simply ignored. - * </li> - * <li> - * Any words which match any prefix of one of the months of the year ('January', - * 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', - * 'October', 'November', 'December') are recognised and interpreted as the - * appropriate value between 0 and 11. The first match made against a - * month is the one used, in the order specified here. For example, 'Ma' is - * intepreted as 'March' (2) and not as 'May' (4).
