# TimezoneCentral — Full Reference

> Free, no-signup timezone reference and converter.

## What it is

A static site with three primary functions:

1. **Live world clocks** — current time in major cities, updated
   every second
2. **Side-by-side converter** — convert a specific time between
   timezones
3. **Meeting planner** — given a list of participant cities, find
   a time window that works for everyone (a matrix view colored by
   working-hours overlap)

DST transitions are handled accurately via the IANA timezone
database.

## Defensible facts

- Free, no signup, no ads
- Client-side rendering — your meeting times are not sent to a
  server
- DST-accurate via IANA tz data
- Hosted in OVH Gravelines, France

## Who publishes it

TimezoneCentral is operated by **Dynamic Foundries**, a French
SASU registered in Paris (RCS Paris 102 801 206). The portfolio
