    If I do something like this:
    QDateTime dt;
    QString updatedTime = NULL;

    dt.setSecsSinceEpoch(0); //zero seconds
    updatedTime = dt.toString("yyyy-MM-dd hh:mm:ss");

    I would expect to get "1970-01-01-12:00.00" but instead I get "1969-12-31 19:00:00". It seems there is an offset that I'm missing.

    Can someone tell me why?

    Thanks

      @leinad said in QDateTime Question:

      Local time (which is what DateTime::toString() outputs)? What timezone are you in?? USA EST (UTC -5 hours) perchance? :)

      Perhaps you are looking to use QDateTime QDateTime::toUTC() const ? See the example code there, and also int QDateTime::offsetFromUtc() const.

          (a) I have already answered and given you the links, and (b) you really ought know what you have to do to a USA time to reach a UTC/GMT/UK time!!!
