docs do not explicitly say that QTimer::start(interval) actually changes the interval also for subsequent starts

#include <QCoreApplication>
#include <QDebug>
#include <QElapsedTimer>
#include <QEventLoop>
#include <QTimer>

int main(int argc, char **argv)
{
    QCoreApplication app(argc, argv);

    QElapsedTimer t;

    QTimer timer;
    timer.setSingleShot(true);
    timer.setInterval(1000);

    QEventLoop e;
    QObject::connect(&timer, &QTimer::timeout, &e, &QEventLoop::quit);

    t.start();
    timer.start(2000); // this is clear, it will trigger in 2000 ms
    e.exec();
    qDebug() << t.elapsed() << "ms";

    t.start();
    timer.start(); // but this is unclear - will it trigger in 1000 or 2000 ms?
    e.exec();
    qDebug() << t.elapsed() << "ms"; // ... and now we can see it was 2000 ms
