go时间转化

将string转化为time.Time

        layout := "2006-01-02 15:04:05"
	str := "2017-11-24 15:10:22"
	a, err := time.Parse(layout, str)
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(a)
	fmt.Println(reflect.TypeOf(a))
	fmt.Println(a.UTC().Format("2006-01-02T15:04:05-0700"))
	fmt.Println(time.Now().UTC().Format("2006-01-02T15:04:05-0700"))
	fmt.Println(time.Now().Format("2006-01-02T15:04:05-0700"))
