Custom Session Background Highlighter (Asia / London / NY)

This was something i am used to using with Motivewave, and did not see a good one with TV. You can set any time frame, and change the background color to any color you want. I like to have a lightly different color background for Asia (6pm to 3am),, London, (3am to 9:30 am) and NY (9:30am to 5 pm). You can set your time as you wish, and change the colors as you like. This was created with the help of ChatGPT and seems to be working perfectly fine, but if you encounter any issues copy and paste the code to chatgpt and ask to revise it as needed.
