I wanted to be able to use Google Earth's time slider to walk through some recent flight data. The other KML export tools I saw didn't use KML's gx:Track extension. That extension is fairly efficient, and Google Earth's time slider is enabled if timestamps are provided. So I wrote a simple Python script.
Here's the github gist, which is easy to modify.

Note the time slider in the upper left. Very handy for examining tricky paths in detail.
Not sure if this forum is the right location. Please advise if tools like these belong elsewhere.
