Recommend a slick meeting-scheduling/appointment-booking site that works globally!

I'm disappointed with Doodle. I'm weary of looking up time-zones and getting the math wrong. I don't want to rifle through a three-column list to see what time it is somewhere else. I don't want to do any of that.

I want a simple web interface that lets me say when I'm available, lets me invite others or everyone, smart enough to know what's on my gCal to not overlap, offers a public-facing view that hides details and just says when I'm free, and a bunch of other cool things I don't know that I need yet.

Who makes it?
