Disclaimer: I have pyqt5 installed and converted it to pyqt4 without testing it in pyqt4...

class MyForm(QtGui.QWidget):
    def __init__(self, parent = None):
        super(MyForm, self).__init__(parent)
        self.lbl = QtGui.QLabel("Clock", self)
        self.lbl.setAlignment(QtCore.Qt.AlignCenter)
        self.lblHidden = False

        vLayout = QtGui.QVBoxLayout(self)
        vLayout.addWidget(self.lbl)
        self.setLayout(vLayout)

        timer = QtCore.QTimer(self)
        timer.timeout.connect(self.flashLbl)
        timer.start(1000)

    def flashLbl(self):
        if self.lblHidden == False:
            self.lbl.hide()
            self.lblHidden = True
        else:
            self.lbl.show()
            self.lblHidden = False
