The original bug describes it best:
When an absolute time is specified to shutdown, the program's
behavior depends on whether that time has passed during the
current calendar day. POLA would suggest that for shutdown,
whose time argument is always supposed to be in the future,
absolute times specified without a specific date should refer
to the next occurrence of that time, rather than erroring out
if that time has already passed during the current day.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
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.

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.
This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.
These tools declare global variables without using the static keyword,
even though their use is limited to a single C-file, or without placing
an extern declaration of them in the proper header file.
It is implemented as a hard link to shutdown(8) and it is equivalent of:
# shutdown -p now
While I'm here put one line of usage into one line of C code so it is easier to
grep(1) and separate unrelated code with empty line.
MFC after: 2 weeks
when halting or rebooting the system. It benefits from
running /etc/rc.shutdown by init(8).
``-o'' flag is provided for backward compatibility.

Discussed with: des
- Make the -k "don't actually halt" flag incompatible with
the halt/reboot options -h, -p, and -r.
- The -n "don't sync" option is ignored if -k is specified.
Issue a warning message.
- Compute the actual shutdown time written to /var/run/nologin
correctly in the case of "now" being specified.
rely on undocumented behavior.
The following fixes were obtained from OpenBSD:
o -Wall fixes to tlist array initialization and assignment used
as truth value.
o Use a restricted environment.
o Improved error message when shutdown fails to exec reboot or halt.
