adfefa527a Issue #23517: Fix implementation of the ROUND_HALF_UP rounding mode in
datetime.datetime.fromtimestamp() and datetime.datetime.utcfromtimestamp().
microseconds sign should be kept before rounding.

5786aef382 Don't abuse volatile keyword in pytime.c
Only use it on the most important number. This change fixes also a compiler
warning on modf().

29ee6745af Enhance _PyTime_AsTimespec()
Ensure that the tv_nsec field is set, even if the function fails
with an overflow.

5ad5821d09 oops, rename pymonotonic_new() to pymonotonic()
I was not supposed to commit the function with the name pymonotonic_new(). I
forgot to rename it.

c3c616c3d1 Issue #24707: Remove assertion in monotonic clock
Don't check anymore at runtime that the monotonic clock doesn't go backward.
Yes, it happens. It occurs sometimes each month on a Debian buildbot slave
running in a VM.

The problem is that Python cannot do anything useful if a monotonic clock goes
backward. It was decided in the PEP 418 to not fix the system, but only expose
the clock provided by the OS.

2ec558739e Issue #23517: datetime.timedelta constructor now rounds microseconds to nearest
with ties going away from zero (ROUND_HALF_UP), as Python 2 and Python older
than 3.3, instead of rounding to nearest with ties going to nearest even
integer (ROUND_HALF_EVEN).

bbdda21a7a Move assertion inside _PyTime_ObjectToTimeval()
Change also _PyTime_FromSeconds() assertion to ensure that the _PyTime_t type
is used.

13019fdef3 Issue #22117: Add a new _PyTime_FromSeconds() function
Fix also _Py_InitializeEx_Private(): initialize time before initializing
import, import_init() uses the _PyTime API (for thread locks).

ea9c0dd2c2 Issue #22117: Fix usage of _PyTime_AsTimeval()
Add _PyTime_AsTimeval_noraise() function. Call it when it's not possible (or
not useful) to raise a Python exception on overflow.

02937aab13 Issue #22117: Add the new _PyTime_ROUND_FLOOR rounding method for the datetime
module. time.clock_settime() now uses this rounding method instead of
_PyTime_ROUND_DOWN to handle correctly dates before 1970.
