UTC World Clock Panel

UTC and world clocks in Chrome's side panel. Convert times, copy ISO timestamps, search by city. No permissions, no tracking.

Your unified time centre. Keep UTC and every time zone you work with in view — docked in Chrome's side panel, beside your work instead of on top of it. Most world clocks are popups: they disappear the moment you click away. This one stays open while you write, review and schedule. Prefer a popup anyway? One click switches it. WHAT IT DOES • UTC pinned at the top as your reference point • Add any of the 400+ IANA time zones, then drag to reorder • Every card shows the local time, date, UTC offset and the gap in plain language — "5h 30m ahead" • Live UTC in the toolbar badge, so you can check the time without opening anything • Two-way converter: set a time in one zone, read it in another, edit either side • One-click copy of a formatted date-time or a valid ISO 8601 timestamp • Light, dark, or follow your system WHAT MAKES IT DIFFERENT No permissions at all. Check the install prompt — it asks for nothing. This extension cannot read, change or even see the pages you visit. Most clock extensions request access to your browsing. Search by city, not by zone ID. "Mumbai", "Bengaluru", "NYC", "Vegas", "Joburg" and hundreds more all find the right zone. Elsewhere you're expected to know that Mumbai lives in "Asia/Calcutta". Timestamps that are actually correct. Copy gives you 2026-09-09T12:08:40+05:30 — genuine ISO 8601 carrying the zone's real offset, with Z used only where the offset is truly zero. Paste it into code, a ticket or a spreadsheet and it parses. Daylight saving done properly. Offsets come from your browser's own time zone database, including the ambiguous hour that happens twice every autumn — the case most implementations get wrong. Day or night at a glance. Each zone is tinted by its local time of day, so you know whether it's a reasonable hour before you call. No account. No sign-in. No network requests. No analytics. No ads. PRIVACY Your zones and settings are saved locally in your browser and never leave your machine. There is no server, and the extension makes no network requests of any kind.
