Are you proposing to put this facility in the kernel? There's already
a perfectly good userspace program to do that - take a peek at
`man hwclock` for details.

There are quite a few people don't bother replying to mailing list
postings that state the poster isn't subscribed to the list, on the

to reply"...

Best wishes from Riley.

PS: The kernel versions page is now back online at the URL below, and
includes separate sublists both for each kernel series, and for
each year of development.
