       /CPUTIME=time

    Specifies the maximum process CPU time for the CPU field of the
    UAF record. The maximum process CPU time is the maximum amount of
    CPU time a user's process can take per session. You must specify
    a delta time value. For a discussion of delta time values, see
    the OpenVMS User's Manual. The default is 0, which means an
    infinite amount of time.
