World Clock

Disclaimer: this project is completely vibecoded.

A small Rust terminal UI that shows the current time across UTC offsets or the full IANA timezone list.

Features

• Live-updating clock display in a terminal UI
• Two views: compact UTC offsets and full timezone database
• Scrollable table with keyboard navigation
• Highlights the local timezone offset and marks yesterday/tomorrow differences

Run

cargo run --release

Install

cargo install worldclock-tui
worldclock

Controls

• q or Esc: quit
• a: toggle between UTC offsets and all IANA zones
• Up / k: scroll up
• Down / j: scroll down
• PageUp: jump up one page
• PageDown: jump down one page
• Ctrl-u: jump up half a page
• Ctrl-d: jump down half a page
• gg or Home: jump to the top

Notes

• Built with ratatui and crossterm
• Timezone data comes from chrono-tz
• If the terminal window is too small, the app shows a resize warning instead of the table
