[time-nuts] M$-Vi$ta-compliant PC RTC clock card?

One factor to remember about good ol' PCs is that not all of the timing
problem is down to the RTC. A lot of timing errors are down to Interrupts. A
busy PC can lose 100s of milliseconds a day as a result of Interrupt
Personally I don't worry about the base accuracy of the PC (RTC or other),
and make sure I'm running NTP linked to a good reference source.

Being a hardware kind of guy, my approach would be a little different.
Why not remove the 32.768kHz crystal and feed the existing RTC with
32.768kHz divided down from a decent oscillator?
Hey, I just thought, maybe there is a market here.
Maybe there is:-)......
