local cmos clock

The local CMOS clock tag covers discussions about Windows time synchronization, particularly when the Windows Time service (w32time) defaults to the local CMOS clock instead of an external NTP source. Common scenarios include domain controllers, especially virtual machines, where the local CMOS clock remains the time source despite configuration attempts. Troubleshooting steps often involve disabling VM time synchronization, re-registering the w32time service, and verifying NTP peer settings. Issues like time drift and synchronization failures are recurring themes, with solutions focusing on ensuring the PDC emulator uses a reliable external time source.
