PerformanceTiming: connectStart property
[!WARNING] This interface of this property is deprecated in the Navigation Timing Level 2 specification. Please use the
PerformanceNavigationTiminginterface 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 establishment start time is given. If a persistent
connection is used, the value will be the same as
fetchStart.
Value
An unsigned long long.
