Project Tools

Do you know what I want? I want an application into which I can input the general timezones of different people, and then save them as groups or project headers. That way I can always have to hand a reminder of the times at which the people with whom I'm working will be the most active.

Doesn't that sound crazy useful for this semi-post-geographical position in which we find ourselves?

Now who knows how to code something like that?
