Not just a hint -- the Red Hat kernel configuration appears

Be careful what you ask for.
This is _not_ a true (time-of-day) timestamp. At least it wasn't last I
looked. Think kernel active time since boot - useful for relative (timed)
occurrences for kernel events.
It would be reasonably trivial to adjust it to a ToD stamp, but it's going to
have some holes
