    Usage: check_fileage -f /mount/path/file.ext -w nnnn -c nnnn [-d A|C|M] [-V] [-h]

    Options:
     -h, --help
     Print detailed help screen
     -d, --datetype
     Date Type: Return the date as defined:
                    A: (time of most recent access),
                    M: (time of most recent content modification),
                    C: (platform dependent; time of most recent metadata change on Unix, or the time of creation on Windows).
                    The default is M.
     -f, --file
     The absolute path and file name.
     -w, --warning
            The age of the file in minutes to generate a warning notification.
         -c, --critical
            The age of the file in minutes to generate a critical notification.
     -V, --version
     State the Version

    Examples:
     check_fileage -f /path/to/file -w 1440 -C 2880
                 Returns OK if the file is less than the warning time in age.
