    Problem with QDateTime setTime_t?


    I've been banging my head with this for a while, I'm sure it will turn out to be a silly thing but I just can't figure it out by myself.

    It seems that QDateTime's setTime_t doesn't behave like I would expect. See the code below:

    QDateTime t1 = QDateTime::fromString("09:30", "hh:mm");
    QDateTime t2;
    QCOMPARE(t1, t2);

    And the outcome is:

    Actual (t1): 1900/01/01 09:30:00.000[local time]
    Expected (t2): 2106/02/07 08:28:15.000[local time]

    I was expecting t1 and t2 to be the same. Can anybody spot what's wrong? I'm using Qt 4.6.2 on Mac OS X 10.6.

    Thanks in advance!

    Never mind. I'm using a test date in year 1900 and time_t counts time starting from 1970...

    Note that there is a copy constructor:
    QDateTime t1 = QDateTime::fromString("09:30", "hh:mm");
    QDateTime t2(t1);
    QCOMPARE(t1, t2);
