Modifies the time value specified with the /BEFORE or the /SINCE
    qualifier. The /EXPIRED qualifier selects files according to
    their expiration dates. (The expiration date is set with the SET
    FILE/EXPIRATION_DATE command.)

    The /EXPIRED qualifier is incompatible with the /BACKUP,
    /CREATED, and /MODIFIED qualifiers, which also allow you to
    select files according to time attributes. If you specify none
    of these four time qualifiers, the default is the /CREATED
    qualifier.
