Mysterious Daylight Savings Time (DST) Changes?

» close window

The Question is:

Why Does the system time change automatically. We have an AlphaStation 255/300
 running VMS 7.1, UCX 4.1-09 and Decnet phase 5. When we change the clock to
 Daylight Savings Time it is changed back to MST shortly after, and not exactly
 an hour change from D
ST. In NCL a SHOW DTSS ALL comes back saying it is not running and we have been
 through utc$time_setup, all looks OK. When we disconnect the Alpha from the
 network and set the time it will not get changed back. Shortly after we
 reconnect to the network th
e time is set back.
1) Can another machine set the time on the Alpha remotely, if so is there a way
 of tracking.
2) Is there another way the Alpha may be looking for the time on the network.
Thank You

The Answer is :

  The TIME audit class in OpenVMS security auditing may be of use here.
  The OpenVMS Wizard strongly encourages an upgrade to OpenVMS Alpha
  V7.1-2 and to TCP/IP Services V5.0A or V5.1 or later -- with ECOs.
  If you have followed the steps listed in the OpenVMS FAQ for setting
  the time and cannot locate local software (DECnet-Plus DTSS or NTP,
  and locally-executed commands such as SET TIME/CLUSTER, being the most
  common causes), please contact the Compaq Customer Support Center for
  assistance in locating and resolving this.
