Golang : Comparing date or timestamp




Problem :

You have to compare two timestamps to see if the they are equal or not.

Solution :

Use time.Equal() function to compare the timestamps. For example :

 package main

 import (
 "fmt"
 "time"
 )

 func main() {

 now := time.Now()

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

 longTimeAgo := time.Date(2010, time.May, 18, 23, 0, 0, 0, time.UTC)

 // compare time with time.Equal()

 sameTime := longTimeAgo.Equal(now)

 fmt.Println("longTimeAgo equals to now ? : ", sameTime)

 // calculate the time different between today
 // and long time ago

 diff := now.Sub(longTimeAgo)

 // convert diff to days
 days := int(diff.Hours() / 24)

 fmt.Printf("18th May 2010 was %d days ago \n", days)

 }

Sample output :

./timecompare

Today : Wed, May 27, 2015 at 12:38am

longTimeAgo equals to now ? : false

18th May 2010 was 1834 days ago
