/sys$common/syshlp/helplib.hlb SET, DIRECTORY, Qualifiers, /CREATED  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /CREATED (default)

    Modifies the time value specified with the /BEFORE or the /SINCE
    qualifier. The /CREATED qualifier selects directories based on
    their dates of creation. This qualifier is incompatible with the
    /BACKUP, /EXPIRED, and /MODIFIED qualifiers, which also allow
    you to select directories according to time attributes. If you
    specify none of these four time qualifiers, the default is the
    /CREATED qualifier.
