Accessing kivy label from Python

[d4py]

Hi, I'm trying to access a label in the kv file.  I would like it to be a clock.  

Currently I have the following code:

from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.button import Button
from kivy.uix.boxlayout import BoxLayout
import time
from kivy.clock import Clock


class test(BoxLayout):
    
    def showClock(self, dt):
         timey = (time.strftime("%H"+":"+"%M"+":"+"%S")),dt
         print(timey[0])
         self.ids.labelID.text = (timey[0])
    event = Clock.schedule_interval(showClock,1)

        


class question(App):
    def build(self):       
        return test()

if __name__ =="__main__":
    question().run()

KV file:

<test>:
    id:test
    
    BoxLayout:
        Label:
            id: labelID
            text:"label"
        Button:
            id: buttonID
            text:"button"
            on_release:test.showClock(1)

If I comment out the event line..  pressing the button changes the label text ok.

Or if I remove the "self", it'll print to the console every second ok.  

However I can't get it to change the label automatically.
It says:

Error:
TypeError: showClock() missing 1 required positional argument: 'dt'

Any help greatly appreciated!
