Summary
The PerformanceTiming.connectStart read-only property returns an unsigned long long representing the moment, in miliseconds since the UNIX epoch, where the request to open a connection is sent to the network. If the transport layer reports an error and the connection establishment is started again, the last connection establisment start time is given. If a persistent connection is used, the value will be the same as PerformanceTiming.fetchStart.
