NTP and Daylight Savings Time? (TDF)

» close window

The Question is:

 
If we use a NTP client in UCX, and the NTP client detects that the time has
 changed from Winter to summer time, how can our processes detect this? Can we
 get any type of interup or somthing from the OS so we know that the time has
 changed?
We programme in Pascal
 

The Answer is :

 
  Your OpenVMS and TCP/IP Services versions are simply too old for this
  capability -- OpenVMS Alpha V7.3 and TCP/IP Services V5.1 have this
  capability built into NTP; the version of NTP included in V5.1 uses
  the TDF event that is first available in OpenVMS V7.3.  For V5.1 on
  earlier versions, the restart of NTP is (as referenced in the FAQ)
  necessary.
 
  Please see the OpenVMS FAQ section on time for general details on
  time, timekeeping, and related topics.  Specifically see the details
  in the FAQ section entitled "Managing Timezones, Timekeeping, UTC,
  and Daylight Savings?"
