How the Grinch Stole Christmas (2000)

Continuity mistake: After the Grinch unscrews the light bulb in the town Christmas tree, all the lights in the town go dark and the Grinch starts to take off in his sled-thing. When they show a close up of him, the lights are on. Then a few seconds later, the lights are off again.

Grinch: Hello!
Grinch's Echo: Hello! Hello! Hello!
Grinch: How are you?
Grinch's Echo: How are you? How are you? How are you?
Grinch: I asked you first.
Grinch's Echo: I asked you first. I asked you first. I asked you first.
Grinch: Oh, that's real mature. Saying exactly what I say.
Grinch's Echo: Exactly what I say. Exactly what I say. Exactly what I say.
Grinch: I'm an idiot.
Grinch's Echo: You're an idiot.
Grinch: [Whispering] All right. Fine. I'm not talking to you anymore. In fact, I'm going to whisper. So that by the time the sound of my voice reverberates off the walls and gets back to me, I won't be able to hear it.
Grinch's Echo: You're an idiot.

Trivia: When the Grinch takes the table cloth from the table, everything on the table was supposed to fall off. When Jim Carrey yanked out the cloth however, everything stayed in place. Jim immediately walked back to the table and improvised knocking everything off and then knocking the table over.

Question: In the beginning, there is a watchman that announces "Another minute closer to Christmas!" as each minute ticks off a countdown clock. Assuming that each panel (days, hours minutes) is on a revolving wheel of some sort, how can the three wheels work correctly in such close proximity to each other? Granted, only the minutes part moves for the sake of the story, but it still begs the question.
