PerformanceTiming.connectStart
This interface of this property is deprecated in the Navigation Timing Level 2
specification. Please use the PerformanceNavigationTiming
interface instead.
The legacy
PerformanceTiming
.connectStart
read-only property returns an unsigned long long
representing the moment,
in milliseconds 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
.
Syntax
time = performanceTiming.connectStart;
