Customize your own listing of timezones from around the world.
As a developer who's worked with many people from around the world, I found it difficult to keep track of what time it was for all my coworkers. I created this extension to simplify that. Right now, Timezone Clocks is simple; you add timezones to your dashboard and give them labels.
I am constantly trying to make this extension better. If you have any ideas or issues, do not hesitate to reach out to me.
