You need to reset all the three values in timeEdit.

This works:

from PyQt4 import QtCore, QtGui

class Help(QtGui.QMainWindow):
    def __init__(self):
        super(Help, self).__init__()

        #QTimeEdit
        self.TimeEdit = QtGui.QTimeEdit()
        self.TimeEdit.setDisplayFormat("hh:mm:ss")
        self.time = QtCore.QTime()
        self.hour = 0
        self.min = 0
        self.sec = 0

        #Hours ScrollBar
        ...
        ...

    def HourChanged(self):
        self.hour = self.HourScrollBar.value()
        self.set_time()

    def MinChanged(self):
        self.min = self.MinScrollBar.value()
        self.set_time()

    def SecChanged(self):
        self.sec = self.SecScrollBar.value()
        self.set_time()

    def set_time(self):
        self.time.setHMS(self.hour, self.min, self.sec)
        self.TimeEdit.setTime(self.time)

...
