    Selects files according to the dates on which they were last
    modified.

    This qualifier is relevant only when used with the /BEFORE or the
    /SINCE qualifier. In addition, do not use /MODIFIED with /BACKUP

    If you omit a time value, TODAY is used. For more information on
    time specifications, see the OpenVMS User's Manual.
