Time

Go has an easy and efficient way of dealing with time. It is flexible, well prepared, and by far the easiest way to produce results.

Measuring Runtime Execution

To measure a runtime execution (not benchmark) for time-sensitive operations on the fly, you can do one of the following recipes depending on your reference points.

Against Current Time

package main

import (

        "fmt"

        "time"

func main() {

        start := time.Now()

        fmt.Println("Hello World")

        duration := time.Since(start)

        fmt.Printf("Time taken: %v\n", duration)

Against 2 Points

package main

import (

        "fmt"

        "time"

func main() {

        start := time.Now()

        fmt.Println("Hello World")

        stop := time.Now()

        duration := stop.Sub(start)

        fmt.Printf("Time start|duration|stop: %v|%v|%v\n", start, duration, stop)

That's all about time package in Go.
