worldclock-tty is a terminal-based world clock that displays local time alongside multiple time zones in real time.
It is particularly useful for users working with people or systems spread across different regions, providing a compact view without requiring a graphical application. Time zones are configurable using standard IANA names, while display options cover sorting, time formats, UTC offsets, colours, themes, military time, and refresh intervals.
This is free and open source software.
Key Features

- Lets you override individual colours for cities, offsets, times, labels, dates, and local time.
- Can save a preferred colour theme as the default.
- Provides commands to add, remove, list, and reset configured time zones.
