title: Why does my MSDOS application show Unix file dates off by 20 days?
body: <p>I have an MSDOS 6.22 application which uses NFS to access files on a Unix server.  It shows file dates 20 days older than the actual file date on the server.   A DIR command shows the same incorrect date.   A Wireshark trace shows that the Unix server does pass the file modification date correctly as seconds since 1970 in the ‘mtime’ field.   Why does the date appear wrong to the DOS applications?</p>
