/EXPIRATION=time (default)
       /NOEXPIRATION

    Specifies the expiration date and time of the account. The
    /NOEXPIRATION qualifier removes the expiration date on the
    account. If you do not specify an expiration time when you add
    a new account, AUTHORIZE copies the expiration time from the
    DEFAULT account. (The expiration time on the DEFAULT account is
    "none" by default.)
