  Disable DTSS automatic daylight time switch? 
 The Question is:
 
How do I prevent DTSS from automatically applying time adjustments for start
 and end of British summertime?
 
 The Answer is:
 
  Use the NCL command:
 
    set dtss automatic tdf change = false
 
  You will see:
 
    Node 0 DTSS
    at [current date and time]
 
    Characteristics
 
        Automatic TDF Change              = False
 
  Or upgrade to OpenVMS V7.3 or later, and leave the automatic
  daylight savings time switchover system parameter disabled.
