We do want to know what these letters are. As an example, the script below is a real-time clock-based clock using a tiny time-lapse camera. It’s not the most effective way to go about this, but in this case, we’re not so worried about it.
The clock is not a clock, it’s just a timer. When it’s running, it will take a little while to get to the time-lapse camera, so you can do that with your own timer. For example, if you want to see what time it takes to start the clock, you could use the timer.
