About TimeZoneCentral

Our Mission

TimeZoneCentral is a free browser-based world clock and meeting planner. It is designed for checking a named time zone now, converting a specific future date, and finding a reasonable working-hour overlap without creating an account.

The site favors an explicit calculation contract over claims of perfect accuracy: results use the time-zone rules installed in the visitor's browser, and important future meetings should be rechecked after governments announce rule changes.

What We Offer

• Live World Clock — current time for named zones supported by the browser.
• Meeting Planner — convert an exact local date across up to six zones, compare neutral working hours, and share the result.
• Time Calculator — add or subtract an interval from the current instant and display the result in a selected zone.
• Developer Formats — Unix, ISO 8601, UTC and selected-zone representations of the same instant.
• City Time Pages — eight live clocks with current offsets, daylight-saving context and source links.
• Reference Guides — a selected abbreviation guide and source-backed UTC vs GMT comparison.

How It Works

Time calculations run in the browser with JavaScript Intl.DateTimeFormat and named IANA zones. The browser or operating system supplies those rules, so their freshness depends on software updates.

The planner rejects local times skipped during a forward clock change and warns when a backward change repeats a local time. See the machine-readable calculation contract.

Privacy

Planner calculations happen locally and request no names, emails or meeting titles. Shareable values live in a URL fragment that is not sent in the HTTP request. Optional Google Analytics loads only after consent, and its configured page location excludes URL parameters.
