Re: cvs commit: src/sys/kern

:On an additional note -- and I suppose anything at this point is 
:nitpicking -- would it be worthwhile to preserve the original 
:drift?  Take an extreme example with the current code with a 
:machine booted at 12:00:00 when the clock adds a second every 30 
:seconds compared to a reference clock:

    No, because the 'drift' isn't necessarily just a drift.  When you
    boot a machine, for example, ntp will throw in a short-lived speed
    up or slow down to get the clock synchronized, but that doesn't
    necessarily mean that the clock is actually running slow or fast.
    When the time is stepped, this sort of correct has to be reset as 
    well.  Also, ntpd expects it, and things would go haywire if it
    weren't reset.
