Overview

Package chronos provides clock functionality that can be useful when developing and testing Cloud Native Buildpacks.

Below is an example showing how you might use a Clock to measure the duration of an operation:

package main

import (
	"os"

	"github.com/paketo-buildpacks/packit/chronos"
)

func main() {
	duration, err := chronos.DefaultClock.Measure(func() error {
   // Perform some operation, like sleep for 10 seconds
   time.Sleep(10 * time.Second)

   return nil
 })
	if err != nil {
		panic(err)
	}

 fmt.Printf("duration: %s", duration)
	// Output: duration: 10s
}
