How does FreeBusy resolve time zone differences?

It's really simple to coordinate meetings across time zones with FreeBusy.
​
FreeBusy automatically detects the time zone of each user when they interact with the service, be it on the Web, in the Outlook add-in or the Chrome Extension.
​
When you schedule and propose meetings with FreeBusy, it automatically translates participant availability to your time zone, so you don't have to do the "time zone math".
