Issue
- A large number of programs disabled due to errors when the controller time changed to February 27, 1990.
- The controller time corrected itself by the next error entry.
Environment
- BCXxxxx
- CX9xxx
- Time Synchronization
Cause
- The system time was changed manually on the Cyberstation that is in charge of administering time synchronization.
- Cyberstation ran a time synchronization routine during the period of time before the time server corrected the system time on the PC.
Resolution
Adjust the user account permissions such that users do not have the ability to change the system time on any Cyberstation PC.
