 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.
