Golang : Calculate future date with time.Add() function

Problem :

You need to calculate future dates by number of days. This can be use in calculating expiring dates or day to execute certain task. How to do that in Golang?

Solution :

Use time.Add() function to calculate the different between today and future date.

For example :

 package main

 import (
 "fmt"
 "time"
 )

 func main() {

 now := time.Now()

 fmt.Println("Today : ", now.Format("Mon, Jan 2, 2006 at 3:04pm"))

 threeDays := time.Hour * 24 * 3

 diff := now.Add(threeDays)

 fmt.Println("Three days from now will be : ", diff.Format(time.ANSIC))

 }

Sample output :

Today : Mon, May 18, 2015 at 11:03am

Three days from now will be : Thu May 21 11:03:31 2015
