Disabling DTSS daylight time switch?

» close window

The Question is:

 
Our Alpha systems automatically turned the clocks back by 1 hour at 1 AM on
 Sunday 21 Oct.
 
We wish to disable this feature; How do we do it?. This coincided with the
 following message in the operator.log:
%DTSS-I-NOMSGS, Message Number 02958403
 
We are running OpenVMS V7.1 on a DEC Alpha 1000A

The Answer is :

 
  You could disable DTSS entirely, per the directions in the OpenVMS
  FAQ.  Or alternatively, you could disable the change:
 
  ncl> set dtss automatic TDF change = false
 
  Or you could select (or newly establish) a timezone rule that does not
  change over to daylight time.  For example, the timezone rule:
 
    EST5
 
  is for a timezone that is five hours behind GMT (US East Coast), and
  that does not change to daylight savings time.
