Data e ora del linguaggio Go (Time)

We can use the Date method provided by the time package to build time objects. The package includes methods such as year(), month(), day(), location(), and so on.

We can call these methods by using time objects.

Go time example

Esempio

package main
import "fmt"
import "time"
func main() {
	p := fmt.Println
	present := time.Now()//current time
	p(present)
	DOB := time.Date(1993, 02, 28, 9, 04, 39, 213, time.Local)
	fmt.Println(DOB)
	fmt.Println(DOB.Year())
	fmt.Println(DOB.Month())
	fmt.Println(DOB.Day())
	fmt.Println(DOB.Hour())
	fmt.Println(DOB.Minute())
	fmt.Println(DOB.Second())
	fmt.Println(DOB.Nanosecond())
	fmt.Println(DOB.Location())
	fmt.Println(DOB.Weekday())
	fmt.Println(DOB.Before(present))
	fmt.Println(DOB.After(present))
	fmt.Println(DOB.Equal(present))
	diff := present.Sub(DOB)
	fmt.Println(diff)
	fmt.Println(diff.Hours())
	fmt.Println(diff.Minutes())
	fmt.Println(diff.Seconds())
	fmt.Println(diff.Nanoseconds())
	fmt.Println(DOB.Add(diff))
	fmt.Println(DOB.Add(-diff))
}

Output:

Esempio di tempo Go 2

Esempio

package main
import (
	"fmt"
	"time"
)
func main() {
	present := time.Now()
	fmt.Println("Oggi : ", present.Format("Mon, Jan 2, 2006 alle 15:04"))
	someTime := time.Date(2017, time.March, 30, 11, 30, 55, 123456, time.Local)
	//Usare time.Equal() per confrontare i tempi
	sameTime := someTime.Equal(present)
	fmt.Println("someTime uguale a now ? : ", sameTime)
	//Calcolare la differenza tra oggi e in precedenza
	diff := present.Sub(someTime)
	//Convertire la differenza in giorni
	days := int(diff.Hours() / 24)
	fmt.Printf("30 marzo 2017 era %d giorni fa \n", days)
}

Output:

Oggi : Mer, 4 ott 2017 alle 17:15
someTime uguale a now ? : false
30 marzo 2017 era 188 giorni fa
