TimeBridge — Instant Time Zone Converter

Overview

TimeBridge started as a fix for one specific annoyance: reading a meeting time written in Norwegian time and having to work out what that meant in Sri Lanka. It grew into a general-purpose converter — select any time on any webpage, right-click, and a floating card appears next to your selection with the converted time and a copy button.

It runs entirely in the browser. No account, no server, no network calls.

Features

• Right-click to convert — select a time on any page and convert it in place via the context menu
• Floating result card rendered next to your selection, with one-click copy and dismiss on Escape
• Toolbar popup with manual entry plus live ticking clocks for your source and target zones
• 20+ time zones across Europe, Asia, the Americas, Africa, the Middle East and the Pacific
• Multi-destination — pick one source zone and several targets, all converted at once
• DST-aware via Luxon and IANA zone names — no hardcoded UTC offsets that break twice a year
• Flexible parsing — handles 09:30, 9:30 AM, 14:00, and Scandinavian dot notation like 09.30
• Settings persist through chrome.storage.sync, so your zones follow your Chrome profile

Tech Highlights

• Chrome Extension Manifest V3 — service worker background script, content script, and popup as separate Webpack entry points
• TypeScript in strict mode throughout, with shared interfaces across the three runtime contexts
• React 18 for both the toolbar popup and the injected floating card, mounted and unmounted on demand
• Luxon for all timezone maths, driven by a table of zone configs rather than branching logic
• A modular parser built on a TIME_PATTERNS array — supporting a new time format means adding one entry, not editing a parser
