You wouldn't be the only one to be confused by this. To solve your problem,
try the following to set the time to 2 Nov 1998 at 10:00am

:setclock date=10/02/98;time=10:00       /* System clock Gradual change   */

:setclock timezone=W5:00              /* Set correct Timezone          */
:setclock ;cancel                      /* Cancel System clock change    */
:setclock date=10/02/98;time=10:00;now   /* Reset System & GMT clocks Now */

The showclks.pubxl.telesup will now look like:

:showclks.pubxl.telesup
SHOWCLKS/XL  A.10.00
DEBUG/iX C.05.08

This shows the GMT to be five hours in front of your time, which is correct.
Once this is setup correctly, you then only have to change the timezone to
change the system time for daylight savings, as a 3600 second correction
will then be in place to change the system time back or forward an hour.
