golang时间格式化

golang中如何输入当前时间

package main
import(
    "fmt"
    "time"
)

func  main(){
    t := time.Now()
    y,m,d := t.Date()
    today := time.Now().Format("2006-01-02")
    datetime := time.Now().Format("2006-01-02 15:04:05")//后面的参数是固定的 否则将无法正常输出

    fmt.Println("time is : ",t )
    fmt.Println("y m d is : ",y,m,d )
    fmt.Println("now is :",today)
    fmt.Println("now is :",datetime)

}
