+<p>A <dfn>connection timing info</dfn> is a <a for=/>struct</a> used to maintain timing information
+pertaining to the process of obtaining a connection. It has the following <a for=struct>items</a>:

+  <dd>A <a for=/>DOMHighResTimeStamp</a>

+  <dd>A <a for=/>DOMHighResTimeStamp</a>
+  <dt><dfn for="connection timing info">connection end time</dfn> (default zero)
+  <dd>A <a for=/>DOMHighResTimeStamp</a>
+  <dt><dfn for="connection timing info">secure connection start time</dfn> (default zero)

Looking deeper, in Chromium it exposes a different timer than connectStart: https://source.chromium.org/chromium/chromium/src/+/master:third_party/blink/renderer/core/timing/performance_resource_timing.cc;l=314?q=secureConnectionStart%20f:.cc&ss=chromium

I think we need to take a look at what implementations are doing and align the spec to that.
