Sorry, but neither statement is correct.
Windows does not read the CMOS clock every second to display the time. It reads it once at startup and then uses a "software" clock routine built into Windows to keep time. Background apps have a tendency to "distract" Windows just enough so the software clock loses time as the day progresses.
Windows resets the clock using "Network Time Servers" which use Atomic Clocks that lose about 1 second every 1,200 years. Internet clocks do not naturally lose time.
I schedule recordings that need to start at EXACTLY the same time every day. I don't want them starting a minute late or ending a minute early.
