Frequently Asked Questions

We implement a modified version of the Olson Timezone Database - a collaborative compilation of information about the world's time zones.

In addition, we use our own systems to resolve queries made on our site in real-time using an innovative fast lookup system.

We've spend innummerable man hours building a mechanism to ensure that the live times you see on your screen are, in fact, accurately synchronised to an atomic clock - perhaps one of the most difficult challenges we undertook in development.

When you view a time page, the World Time Engine takes a few seconds to calibrate your location and browser before we're satisfied that we've synchronised it with the atomic time.

Once this calibration is complete the clock changes to show you seconds ticking by in your browser. This is the currently synchronised time.

We're confident that the dynamic time we provide is accurate to within 2 seconds of atomic time at any given location on earth.

We offer licensed personal and commercial use of our data through the World Time Engine Local API Service™.

For commercial licensing options beyond the standard API Terms of Use, please contact us for more information.

We are continually tweaking and refining our API to meet the needs of our users and any feedback you may have is essential to continuing to provide the best Time API available anywhere in the world.
