This thread is pretty much self-explanatory for the most part...........you, the poster, can brainstorm time zone layouts, abbreviations, and even trivia, etc., of any number of timelines you choose.........even your own! However, the one general rule of thumb here is: the more details, the better. And I suggest starting out with just countries and maybe a continent, and then the whole world.
I'll try to post my first one soon............have fun.
