Y2K Compliance

• Wssindex believes what the operating system tells it about dates. Nothing can be guaranteed if the OS has Y2K problems.
• Wssindex stores dates in the same format as is used in a FAT directory entry, i.e., 7 bits represent the number of years since 1980. This breaks in 2108, and may eventually be considered as shortsighted as the use of 2-digit years, but Wssindex can do no better than the underlying file system.
• Wssindex displays only 2-digit years. This should not be ambiguous because valid file dates must be in the range 1980-present. But, a file may, by accident or design, be given a date stamp far in the future. Options for 4-digit year display will appear in the next release of Wssindex.
• When Wssindex prompts for a date, it appears to be asking for a 2-digit year. But, 4-digits can be entered. This will be made clear in the prompts for versions after 6.01.
• If a 2-digit year xx less than 80 is entered, it is assumed to be 20xx; a 2-digit year xx greater than or equal to 80 is assumed to be 19xx.
• Wssindex does not do any leap year calculations.
