in January 2009 (the Christos' time merge, when time_t went to 64 bits).
sysctl needs to catch up. (So do other progs, which will happen, eventually,
but most of them are unaffected in any practical way.)
If you are running a system (NetBSD 6 or later) without this change, try
sysctl -nn kern.boottime
and marvel at the result (in theory, seconds.microseconds) most
probably being something like:
jinx$ sysctl -nn kern.boottime
1540801874.999995564
(There is a 1 in 1000 chance your system will have booted
in the interval [0 , 999999] nanoseconds after some second,
in which case this will not be observed. You should get
(almost) the same value after this change - just now it is as
it should be (there should now always be 9 digits after the '.').
On the other hand, if you're on a big-endian 64 bit host (running
64 bit sysctl) you would have always seen 0 for the microseconds field.
That should be fixed by this.
In sysctl(7) also document what we mean by "the time the system booted".

identd has aliasing violations, use -fno-strict-aliasing.
newfs_msdos's getbpbinfo() has missing {} issues.
sysctl's kern_cp_id() has missing {} issues.
sysctl variable using ?= fails with EPERM, don't print an error
message.
Ideally setting a sysctl to the same value it already has should also
not fail regardless of permissions, but this would need to be done in
the kernel.
sysctl.7. Remove the list of MIBs from sysctl.8 so we don't have to
maintain duplicate information, as proposed by YAMAMOTO Takashi on
tech-userlevel. Also remove references to header files from sysctl.8.
The numeric constants remain documented, they are still needed in some
cases. See the discussion on tech-userlevel. ("mib list in sysctl.8")
OK by YAMAMOTO Takashi.
