[feature] Display all timezones

[chris-aeviator]

When first coming to this repository I found

particulary appealing since I expected ´tz´ without further arguments to display

A) a list of all timezones
B) timezones at night having a dark background / timezones currently in daytime having a light background

I think both would make for useful features. Could you think of implementing this?

When running ´tz´ I will see my timezone compared to only UTC with a dark background currently.

Thanks for opening this issue!

The screenshot illustrates that the program works on both light and dark terminal backgrounds. Sorry for the confusion. 🙇🏻

Currently, the text color for the hours displayed approximates the day/night cycle to guide you a bit, but there are no plans to change the background colors based on the time in a different time zone.

As I don't need the feature myself, I won't be implementing it but I'll review PRs from time to time. 🙏🏻
