Chrono is a fully-fledged version if its' younger brother, chrono-lite.
The lite version is great for hosting on your own, and forking to make your own changes. However, for the best effect, I reccomend getting Chrono proper, as it has many more features designed to help guilds and users much more.
Unlike other bots, it's non-intrusive and easy to use! Integrate the power of https://lmgtfy.com/?q=time+zone+converter into your Discord chat bar!
