The text that you quoted above, because some hardware platforms do not
contain a hardware clock that can be set to either.
>I said that it can support what the platform supplies.
You said more than that; you made a claim as to how it could be set.
>Again, I stated that OS can support what the platform supplies.
Again, you stated more than that.
>So a TOD clock does not supply the time of day?
Red herrings! Get your red herrings while they're fresh. I didn't say
that the TOD clock can't supply the time of day; I said that tw
different pieces of hardware weren't supplying the same function.

Only with some of the platforms that supply hardware clocks.

There are only two timing facilities; CPU and TOD. The clock
comparator compares the value in the TOD clock.

There is nothing in the PoOps about a third clock.
>Is the TOD clock like a RTC/CMOS clock?
Which? The PC has several different timing facilities.
