    Red face [SOLVED] QDateTime (revisited)

    Hi,

    I have this 32 bit value which represents the number of seconds since 1989-12-31 00:00:00

    Looking at the fxs:
    toTime_t ()
    fromTime_t ()

    Their starting date is 1970-01-01T00:00:00

    I've tried:
    Qt Code:
    1. QDateTime dateTime;
    2. QDateTime dateTimeStart;
    3.  
    4. //! \note Date/Time starts at 1989-12-31 00:00:00
    5. dateTimeStart = QDateTime::fromString("M12d31y8900:00:00", "'M'M'd'd'y'yyhh:mm:ss");
    6. quint16 start = dateTimeStart.toTime_t();
    7.  
    8. dateTime=QDateTime::fromTime_t ( driver_id_data.status_change_time + start );
    9. humanDate = dateTime.toString ( "yyyy-MM-dd hh:mm:ss" );
    To copy to clipboard, switch view to plain text mode 

    This obviously fails due to the nature of fromTime_t() and toTime_t() ...

    So the real question here is:
    How can I add that 32 bit value to dateTimeStart ?

    TIA,
    Pedro Doria Meunier

    ooooops! My bad!

    I should have :
    Qt Code:
    1. quint32 start = dateTimeStart.toTime_t();
    To copy to clipboard, switch view to plain text mode 

    instead of:
    Qt Code:
    1. quint16 start = dateTimeStart.toTime_t();
    To copy to clipboard, switch view to plain text mode 

    Deeply sorry for the noise ...

    BR,
    Pedro.
