软件包: node-performance-now (2.1.0+debian-1)

Implements performance.now (based on process.hrtime)

Modern browsers have a `window.performance` object with - among others - a `now` method which gives time in milliseconds, but with sub-millisecond precision. This module offers the same function based on the Node.js native `process.hrtime` function.

Using `process.hrtime` means that the reported time will be monotonically increasing, and not subject to clock-drift.

This library is a dependency of request, the simplest way possible to make http calls.

Node.js is an event-based server-side JavaScript engine.
