By specification, date conversion functions for dates before the epoch are not DST corrected. We converted QTime to a QDateTime where we set the date part to Jan. 1, 1970, and then convert that to msecs since the epoch UTC. For places on Earth where they had DST on that day (e.g. Hobart in Australia), strange things happen: conversion from a QTime to DateObject will use DST (because it's after the epoch in local time), but conversions from DateObject to QTime won't use the DST because it's before the epoch (in UTC). Now as everyone knows, a 24-hour clock time has no meaning without a date, only "elapsed time" has. But users still expect to be able to pass QTime to QML/JS. So, we do the conversion on day 0 of month 0 of year 0, and all of it in local time. This gives a stable conversion in both directions, and the values in both C++ and QML/JS are the same for any timezone (with or without DST) on this planet.

README
This directory contains autotests and benchmarks based on QTestlib. 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.
