I've just received an email that contains a remotely hosted animated png. The png file is a countdown timer. Here is the URL:-

Can someone please help me explain how this works? I would have expected that each time I load the file it would start playing fomr the same point, effectively resetting the countdown, but that seems not the be the case.
How does the PNG file know where to resume it's countdown from?
