Synchronizing the System Time
The preconfigured system contains the :SYNC utility to update the system time. It must be run as manager.
...
- By default, :SYNC performs a :SETCLOCK;NOW to adjust any large discrepancies between the system clock, and the current time. It should only be used when starting or resuming an emulated system, and should not be used while date-aware programs or command files are running.
- :SYNC should not be used at or close to midnight - this could result in an incorrect date being set.
- :SYNC is supplied 'as-is', with no warranty as to correct performance.
