The format is chromium's: 
https://www.chromium.org/developers/how-tos/trace-event-profiling-tool/

If you use the Chrome browser, go to `about:tracing`.
See here for some screenshots of what it looks like:

I have not yet seen a tool that converts it into ASCII as you 
propose, might be a nice project for someone to work on :)

(the chromium time trace format is used by other tools too, 
notably Clang, so the ASCII tool would be appreciated by more 
than just LDC users)

cheers,
