timezone offset. These values are generally zero.
While one still theoreticall could set these values, that's almost
never done. Users wishing to have an offset between the time of day
clock hardware and UTC use adjkerntz(8) instead.
localtime(3) should be used to find these values for the current
timezone.
Contrary to the removed comment, the kernel does appear to use the timezone
argument of settimeofday. The comment dates to the BSD4.4 import; I assume it
is just stale.
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

(CLOCK_REALTIME case) system calls is non negative.
This commit hides a kernel panic in atrtc_settime() as the clock_ts_to_ct()
does not properly convert negative tv_sec.
ps. in my opinion clock_ts_to_ct() should be rewritten to properly handle
negative tv_sec values.

Depending on system configuration and parameters, clock_gettime() and
gettimeofday() may not be system calls. If so, passing an invalid pointer
will cause a signal and not an [EFAULT] error.
From a standards perspective, this is OK since passing an invalid pointer is
undefined behaviour.

Stop calling system calls "function calls".
Use "The .Fn system call" a-la "The .Nm utility".
When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.

before, but the most accurate way of describing the funcionality eludes
me.

Use the correct .Bx (BSD UNIX) or .At (AT&T UNIX) macros
instead of explicitly specifying the version in the text
in a bunch of man pages.
