[Pygame] Making a clock

[Dialtone]

Hi all, I'm trying to make a clock with pygame and python2.2 but I have a
problem in rotating the pointer.
The image is the pointer, and quadrante is the clock. The code below is
just supposed to rotate of 6 degrees CW the pointer but I don't manage
to... 
I've also tried without the class using a main() and an update() functions
 to create and manage the clock, but either way it doesn't work...
where am I mistaken?

class orologio:
    def __init__(self):
        self.quadrante = pygame.display.set_mode((256,256))
        self.image = pygame.image.load('~/Documents/lancetta.jpg')
	self.image = self.image.convert()
        self.axis = (128,128)
        self.quadrante.blit(self.image, [126,0])
        pygame.display.flip()
        self.second_degree = -6
        self.quadrante = rotate_with_axis(self.quadrante, self.second_degree, \
								self.axis)
        self.quadrante.blit(self.quadrante, self.quadrante.get_rect())
        pygame.display.flip()

def rotate_with_axis(surf,angle,axis):
    """rotates image by angle degrees CCW, and returns a surface the
    same size as the input image.
 
    new pixels may be visible in the result that weren't in the
    original image. see
    http://www.pygame.org/docs/ref/pygame_transform.html#rotate for
    the rules about those"""

    # make a bigger surface padded such that the axis point is in the center
    paddedsize=[max(anaxis,asize-anaxis)*2 for anaxis,asize in \
								zip(axis,surf.get_size())]
    padded=pygame.Surface(paddedsize,0,surf)
    padded.blit(surf,[ps//2-a for ps,a in zip(paddedsize,axis)])
    # rotate the big image
    rotated=pygame.transform.rotate(padded,angle)
    # cut out the appropriate piece of the larger rotated image
    newtopcorner=[rs//2-a for rs,a in zip(rotated.get_size(),axis)]
    return rotated.subsurface(pygame.Rect(newtopcorner+list(surf.get_size())))

if __name__=='__main__':
    pygame.init()
    clock = orologio()
    time.sleep(10)
