meaning of all_ms vs all_end

Web Performance Discuss Test Results
1

I am running tests programatically against a private instance of wpt, The json results include this:

"all_end": 482, "all_ms": 228, "all_start": "236",

How do all three relate to each other? I would have expected

all_start + all_ms = all_end

but the math doesn’t work out.

Looks like the code for it is here: webpagetest/object_detail.inc at master · WPO-Foundation/webpagetest · GitHub

Do you know if the requests in question had any dns or socket connect times? It looks like those might cause the results to change (though I still wouldn’t expect it to do what you are seeing).

ok, I can see how this might be a bug or something ; I can let this go. I just wanted to make sure that at least my expectations are correct.
