An error of 5000 ppm is way way off. Something is broken. I don't know if
it's hardware or software.
If you have a scope or counter, you should be able to sanity check the
A couple generations back, the RTC used to live off in a separate big boxy
"chip" with a crystal and battery all included. Most modern boards have the
RTC in a corner of the southbridge chip with a battery and crystal nearby.
Look for a 32 KHz watch crystal.

Keeping idiots from shooting themselves in the foot is probably the first
step in making life harder for virus/trojan writers.

I've seen comments about people going out to buy a couple of copies of an
older MS operating system in order to avoid problems like this.
These are my opinions, not necessarily my employer's. I hate spam.
