A recent post on a bulletin board (I can’t remember where) claimed that Google Earth Enterprise Client already has the fabled time browser built in — it’s just that none of us have used Enterprise Client as it is part of an industrial-strength solution that is most certainly not free.

I couldn’t find any mention of a time browser on the product page, so I asked Google Earth’s director of engineering Brian McClendon if the time browser exists. Here is what he wrote back:

GE-EC (the client software) does have a time menu that adds an additional visiblity filter based on a animatable slider.

But Brian says that it isn’t ready for prime time yet; this means we’ll need to wait before it arrives in other versions of Google Earth.
