Properties #

readonly
#bootstrapComplete: number

The high resolution millisecond timestamp at which the Node.js process completed bootstrapping. If bootstrapping has not yet finished, the property has the value of -1.

readonly
#entryType: "node"
readonly
#environment: number

The high resolution millisecond timestamp at which the Node.js environment was initialized.

readonly
#idleTime: number

The high resolution millisecond timestamp of the amount of time the event loop has been idle within the event loop's event provider (e.g. epoll_wait). This does not take CPU usage into consideration. If the event loop has not yet started (e.g., in the first tick of the main script), the property has the value of 0.

readonly
#loopExit: number

The high resolution millisecond timestamp at which the Node.js event loop exited. If the event loop has not yet exited, the property has the value of -1. It can only have a value of not -1 in a handler of the 'exit' event.

readonly
#loopStart: number

The high resolution millisecond timestamp at which the Node.js event loop started. If the event loop has not yet started (e.g., in the first tick of the main script), the property has the value of -1.

readonly
#nodeStart: number

The high resolution millisecond timestamp at which the Node.js process was initialized.

readonly
#v8Start: number

The high resolution millisecond timestamp at which the V8 platform was initialized.
