    Default Time Differential Factor for standard time is -5:00.
    Default Time Differential Factor for daylight saving time is -4:00.


    The Time Differential Factor (TDF) is the difference between your
    system time and Coordinated Universal Time (UTC).  UTC is similar
    in most repects to Greenwich Mean Time (GMT).

    The TDF is expressed as hours and minutes, and should be entered
    in the hh:mm format.  TDFs for the Americas will be negative
    (-3:00, -4:00, etc.); TDFs for Europe, Africa, Asia and Australia
    will be positive (1:00, 2:00, etc.).            

    If this is a seasonal time change, it may also be necessary to
    modify the system time.  Generally, seasonal time changes result
    in adding 1:00 hour, or adding -1:00 hour to the system time.

    Enter the time adjustment value you would like to add to
    the local time.  You can enter hours only (hh) or hours and
    minutes (hh:mm)  The value can be positive (hh:mm or +hh:mm)
    or negative (-hh:mm).          

    NEW SYSTEM TIME DIFFERENTIAL FACTOR = -4:00
    ADDING -1:00 TO THE LOCAL TIME.

        This procedure queues a batch job that changes the system time
        and system time differential around a daylight saving time
        change.  Press the question mark (?) key at any time for help;
        hit Control-C to exit.

        The Time Differential Factor (TDF) is the difference
        between your system time and Coordinated Universal Time (UTC).
        The difference is expressed in hh:mm format.  The Americas
        have negative offsets from UTC, while Europe, Africa, Asia
        and Australia have positive offsets from UTC.

       * Enter the Time Differential Factor: -4:00

        If this is a seasonal time change, it may also be
        necessary to modify the system time.  Generally,
        seasonal time changes result in adding 1:00 hour,
        or adding -1:00 hour to the local time.

        * Do you wish to modify the local system time [N]: Y 

        Enter the time value you would like  to add to
        the local time.  The value can be a positive or
        a negative (-hh:mm) value.

        * Enter the time value: +1:00 

        The process to modify your time zone offset and local
        time (if supplied) can occur now or in the future.
        Press Return to run the job now.

        * Enter the run time in the DD-MMM-YYYY:HH:MM:SS format:
