Lightworks Tutorial: Adding a timer to specific points in your video

I wanted to create a video showing the loading time of a game, but couldn&find any tutorials online that does what I wanted. I need a timer that allows me to start the counting at a specific time in the video, and stop at a specific time. So I explored Lightworks on my own and mess around with the features a bit, and found out a way to do it. A good method if you&doing speedrun gaming videos, or comparing boot up times of two phones/tablets, etc.
