go 时间和日期 格式化

 

    t:=time.Now()

    fmt.Println(time.Now())
    fmt.Printf("%4d %02d %02d\n",t.Year(),t.Month(),t.Day())
    fmt.Printf("%02d.%02d.%4d\n", t.Day(), t.Month(), t.Year())

    t = time.Now().UTC()
    fmt.Println(t)

    fmt.Println(t.Format(time.RFC822)) // 21 Dec 11 0852 UTC
    fmt.Println(t.Format(time.ANSIC)) // Wed Dec 21 08:56:34 2011
    fmt.Println(t.Format("02 Jan 2006 15:04")) // 21 Dec 2011 08:52
    s := t.Format("20060102")
    fmt.Println(t, "=>", s)

    s = t.Format("20060102 15:04:05")
    fmt.Println(t, "=>", s)
