The code snippet below demonstrates various examples of using the time package, and you can try it out here (opens in a new tab).

package main
 
import (
	"fmt"
	"log"
	"time"
)
 
func main() {
	now := time.Now()
	fmt.Println(now) // prints the current time
 
	t := time.Date(2023, time.January, 3, 14, 26, 23, 0, time.UTC)
	fmt.Println(t) // 2023-01-03 14:26:23 +0000 UTC
 
	start := time.Now()         // start time
	time.Sleep(time.Second * 2) // Sleeps for 2 seconds
	end := time.Now()           // end time
 
	duration := end.Sub(start) // calculates the time difference between start and end
	fmt.Println(duration)      // prints the time difference
 
	t1 := time.Date(2020, time.October, 11, 9, 54, 32, 0, time.UTC)
	t2 := t1.Add(time.Minute * 3) // Adds 3 minutes to t1
 
	if t1.Before(t2) {
		fmt.Println("t1 is before t2")
	}
 
	t1Str := t1.Format(time.RFC822Z) // 11 Oct 20 09:54 +0000
	fmt.Println(t1Str)
 
	t1Parsed, err := time.Parse(time.RFC1123, "Sun, 11 Oct 2020 09:54:32 UTC")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(t1Parsed)
}
