bpo-31327: Update time documentation to reflect possible errors (GH-31460)
As per the comments, this mirrors the [datetime documentation](https://docs.python.org/3/library/datetime.html#datetime.datetime.fromtimestamp). 

```
>>> import time
>>> time.localtime(999999999999999999999)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: timestamp out of range for platform time_t
>>> time.localtime(-3600)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 22] Invalid argument

[docs] Use full names for time units (GH-28611)
Use "second", "millisecond", "microsecond", "nanosecond" instead of
"sec", "ms", "msec", "us", "ns", etc.

bpo-21302: time.sleep() uses waitable timer on Windows (GH-28483)
On Windows, time.sleep() now uses a waitable timer which has a
resolution of 100 ns (10^-7 sec). Previously, it had a solution of 1
ms (10^-3 sec).

* On Windows, time.sleep() now calls PyErr_CheckSignals() before
  resetting the SIGINT event.
* Add _PyTime_As100Nanoseconds() function.
* Complete and update time.sleep() documentation.

bpo-43407: Clarify comparisons of time.monotonic() et al results (GH-24757)
Previous wording implied that only the result of call N and N+1 could be
meaningfully compared, whereas comparing call N and N+M is fine.

bpo-37205: time.perf_counter() and time.monotonic() are system-wide (GH-23284)
time.perf_counter() on Windows and time.monotonic() on macOS are now
system-wide. Previously, they used an offset computed at startup to
reduce the precision loss caused by the float type. Use
time.perf_counter_ns() and time.monotonic_ns() added in Python 3.7 to
avoid this precision loss.

Michael Wayne Goodman 91874bb071 closes bpo-39135: Remove 'time.clock()' mention in docs. (GH17709)
`time.clock()` was removed in Python 3.8, but it was still mentioned
in the documentation for when `time.get_clock_info()` is given the
argument `'clock'`. This commit removes that mention.

Callum Ward 42bc60ead3 closes bpo-29275: Remove Y2K reference from time module docs (GH-17321)
The Y2K reference is not needed as it only points out that Python's use
of C standard functions doesn't generally suffer from Y2K issues; the
point regarding conventions for conversion of 2-digit years in
:func:`strptime` is still valid.

Éric Araujo 1b1d0514ad fix link to time function from time_ns doc (GH-15285)
Because mod, func, class, etc all share one namespace, :func:time creates a link to the time module doc page rather than the time.time function.

Matthias Bussonnier e2500610c6 bpo-36895: remove time.clock() as per removal notice. (GH-13270)
`time.clock()` was deprecated in 3.3, and marked for removal removal in
3.8; this thus remove it from the time module.

bpo-31784: Implement PEP 564: add time.time_ns() (#3989)
Add new time functions:

* time.clock_gettime_ns()
* time.clock_settime_ns()
* time.monotonic_ns()
* time.perf_counter_ns()
* time.process_time_ns()
* time.time_ns()

Add new _PyTime functions:

* _PyTime_FromTimespec()
* _PyTime_FromNanosecondsObject()
* _PyTime_FromTimeval()

Other changes:

* Add also os.times() tests to test_os.
* pytime_fromtimeval() and pytime_fromtimeval() now return
  _PyTime_MAX or _PyTime_MIN on overflow, rather than undefined
  behaviour
* _PyTime_FromNanoseconds() parameter type changes from long long to
  _PyTime_t

DeprecationWarning warning.

is now always available since Python 3.5.
