PerformanceTiming: connectStart property

View on MDN ↗

[!WARNING] 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 establishment start time is given. If a persistent connection is used, the value will be the same as fetchStart.

Value

An unsigned long long.
