Hi,
I think this has something to do with the conversion of float timestamps to integer millisecond values. I couldn't figure out how to fix it properly last time I looked at it. I'll put it back on my list of things to do. With school starting, I can't promise much more.
If you turn off validation, everything should work fine. I'm assuming you're using the
softwareishard.com HAR viewer?
PS: I get a 403 forbidden with your link.
