Create a function here called timingForSocket(socket) that can read values that were set through symbols to avoid clashing with proper fields. Basically, encapsulate the internal symbols to this file.

Adds some instrumentation to collect timings for APIRequestContext requests and adds them to the HAR trace. Doesn't yet expose them via an API, but makes our Duration field in the trace viewer show a nice duration:

I'm gonna add it to our API in a separate PR.

Create a function here called timingForSocket(socket) that can read values that were set through symbols to avoid clashing with proper fields. Basically, encapsulate the internal symbols to this file.

Good catch. I've replaced firstByteAt with a measure of when the response headers are sent in 5d8ab8a. I think that's more in-line with the HAR definition anyways.
