Accurate time, without the clutter

True Time Converter is a world clock, a time zone converter and a meeting planner in one fast page. It exists because most time tools are either bloated with ads, stuck with hardcoded daylight saving rules, or require an account to remember two cities.

Data you can trust

Every clock, conversion and DST warning on this site is computed through your browser's native implementation of the IANA time zone database — the same source that powers computers, phones and servers worldwide. When daylight-saving rules change anywhere on Earth, your browser picks up the update and so do we. We never hardcode offsets.

No accounts, ever

Your selected cities, home city and preferences are stored locally in your browser (via localStorage). Sharing a view generates a plain URL that contains everything the other person needs — no tracking, no sign-up, no database.

Features

• Compare up to 12 cities on one timeline with hover-scrub
• Business-hours highlighting and the shared working window
• Meeting planner that ranks the best overlap times
• Google Calendar, Outlook and .ics export — no OAuth required
• Shareable links with cities, date, hour and settings baked in
• 12/24-hour display, weekend markers and a live "now" line

Made to stay fast

The whole tool is a single static page with a few kilobytes of JavaScript. No frameworks, no cookies, no ads.
