Apparently, On Wed, Aug 07, 2002 at 03:00:02PM -0400,

Hmm.  I guess this is due to the definitions of these sysctls in
kern/subr_clock.c using OID_AUTO, instead of the correct hard coded
oid values.  The numbers should be the same everywhere, and they can't
change without breaking the abi.

Thanks for pointing this out, I'll fix it.
