'Relative Data, Inc.' was incorporated in 2000. Previously it was known as 'Relative Data Products'. It is driven by me, David Patte, of Ottawa Canada.
Our first product was 'MyStars!', written in C, then C++, and released via BBS systems, then via the internet in the 90s. It was the first commercial star map product designed for Windows, and has been registered by thousands of users around the world. Our last formal release of MyStars! (v2.7) was in 2001, though we are still toying with the thought of releasing a new version.

Relative Data launched its first website in 1996, being an early adopter of website technology.
At the current time we host over 25 domains on our server space, including many sites we have fully developed for our clients using Drupal. Many sites have custom PHP modules, or unique back-end C++ code we have written to provide complex functions and calculations. We also act as a payment gateway, for online retail selling, for some of our clients. Read more »
Time Zone Master is a new Windows Clocks program from Relative Data.
A Windows Clock Program Done Right
There are literally hundreds of clock display programs available for Windows. But virtually all of them use Window's own timezone database of UT offsets and daylight saving/summertime rules. But what happens when countries or regions then change to different clock rules? Windows timezone database, and windows clock programs that depend on it, are then wrong and can remain wrong for as long as six months before Microsoft updates their database! Certainly, most Windows clock programs are not something to depend on!
By Using the Olson Zoneinfo tz Database
Instead, Time Zone Master internally uses the comprehensive Olson Zoneinfo tz database, maintained using input from hundreds of corporate contributors worldwide, and used on Linux servers. Whenever any regional clock law change become known and confirmed, the database is quickly updated! Time Zone Master can then automatically download and install these updates within hours, not months! With Time Zone Master, your displayed clocks will always be as accurate as possible; now, and into the future!
It's also a Unique Astronomy and Timezone Research Tool
Time Zone Master adds over 200 countries, and over 45,000 towns and cities to its database, making it easy to select your clocks!
But far more than just a clock display program, Time Zone Master then adds all known historical timezone rules for 300 different world timezone regions going back to at least 1970, and for primary cities in these regions back to before the mid 1800s, making accurate historical time-of-day research possible! In comparison, windows built-in timezone database has NO historical timezone rules data.
Finally, Time Zone Master is also a highly accurate astronomical clock, showing Sunrise/Sunset, Moonrise/Moonset, the times of moon phases, and the start of the seasons, the local Mean Time, Equation of time, Solar Sundial Time, Sidereal Time, and Terrestrial Time for each Read more »
