No, this doesn't look like the "fast CPU" problem you are alluding to
(look for subject MODVERSIONS in the archives). We fixed that one.

Your problem is that your kernel source dir (unpacked tarball?)
contains files with time stamps several hours in the future;
'make' doesn't take kindly to this.

I've seen this happen once: during an upgrade (RH-style, i.e. not
fresh install) from RH6.2 to RH7.0, my /etc/localtime had become
overwritten and my machine in an instant moved from CET to some US
time zone 6 or 8 hrs back. Then when I unpacked my kernel tarball to
build a real kernel, I got exactly the problems you listed above.

Check your clock & time zone settings.
