In C++20, QDateTime is a direct equivalent of a sys_time<milliseconds> time point. (Before, it might not have been, because system_clock before C++20 was not guaranteed to be tracking Unix time, AKA UTC time without leap seconds.) To be specific, sys_time<milliseconds> corresponds to a QDateTime using the Qt::UTC timespec. This patch: 1) adds named constructors taking time_points: * a generic one taking any time_point convertible (via clock_cast) to a system_clock (this obviously includes system_clock, but also e.g. utc_clock) * another couple taking local_time, interpreted as a duration from 1/1/1970 in local time. 2) adds a named constructor from zoned_time (i.e. a sys_time + a timezone), that we can easily support via QTimeZone. 3) add conversion functions towards sys_time, matching the existing to(M)SecsSinceEpoch() functions. [ChangeLog][QtCore][QDateTime] QDateTime can now be constructed from std::chrono::time_point objects (including local_time), as well as from std::chrono::zoned_time objects. Moreover, they can be converted to std::chrono::time_point using system_clock as their clock.

README
This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
