Set and print Daylight Savings Time

The daylight savings time adjustment can be programmed to take place automatically. You can set the date to change to daylight savings, and to return to standard time. This information can be queried at any time. The following commands are accepted by this program for this capability.

• The system clock MUST ALREADY be set for the daylight savings time to be updated.
• This information survives sysload:
  • FWTM = Set the date and time for the clock to move forward.
  • BWTM = Set the date and time for the clock to move backward.
  • SDST = Enable or disable the automatic change.
  • TDST = Query the change information.
