Set a flag when you print the text to indicate that you've already
printed it, and don't print it again if the flag is set.  When it's no
longer 12:00:00, reset the flag.

That said, a busy while loop is probably the wrong way to do this,
because it will run your CPU at 100%.  Better would be to put the
thread to sleep with time.sleep() calls or a real event loop with a
timer event.
