golang time使用

[hapiman]

• 当前时间戳
  fmt.Println(time.Now().Unix())

• 当前格式化时间
  fmt.Println(time.Now().Format("2006-01-02 15:04:05"))

• 时间戳转str格式化时间
  str_time := time.Unix(1389058332, 0).Format("2006-01-02 15:04:05")

• str格式化时间转时间戳

the_time := time.Date(2014, 1, 7, 5, 50, 4, 0, time.Local)
unix_time := the_time.Unix()
fmt.Println(unix_time)

• 使用time.Parse

the_time, err := time.Parse("2006-01-02 15:04:05", "2014-01-08 09:04:41")
if err == nil {
        unix_time := the_time.Unix()
	fmt.Println(unix_time)		
}

func testTime() {
	//获取时间戳
	timestamp := time.Now().Unix()
	fmt.Println(timestamp)
	//格式化为字符串,tm为Time类型
	tm := time.Unix(timestamp, 0)
	fmt.Println(tm.Format("2006-01-02 03:04:05 PM"))
	fmt.Println(tm.Format("02/01/2006 15:04:05 PM"))

	const longForm = "2006-01-02 15:04:05"
	tt, _ := time.Parse(longForm, "2018-03-12 23:11:00")
	tt2, _ := time.Parse(longForm, "2018-03-12 23:08:00")
	ttValue := tt.Unix()
	tt2Value := tt2.Unix()
	fmt.Println("ttValue - tt2Value =", ttValue-tt2Value)

	t := time.Unix(1362984425, 0)
	nt := t.Format("2006-01-02 15:04:05")
	fmt.Println(nt)

	const TimeFormat = "2006-01-02 15:04:05"
	t2, _ := time.Parse(TimeFormat, "2013-08-11 11:18:46")
	fmt.Println(t2)

	// c := time.Tick(1 * time.Second)
	// for now := range c {
	// 	fmt.Printf("%v %s\n", now, "ss")
	// }

	unixSeconds := time.Now().Unix()
	fmt.Println("unixSeconds =>", unixSeconds)

	tm2, _ := time.Parse("2006-01-02 00:00:00", "2018-03-12 14:00:00")
	fmt.Println("tm2.Unix =>", tm2.Unix())

	year, month, day := time.Now().Date()
	fmt.Println("Happy Go day!", year, month, day)

	ticker := time.NewTicker(time.Second)
	defer ticker.Stop()
	done := make(chan bool)
	go func() {
		time.Sleep(10 * time.Second)
		done <- true
	}()
	for {
		select {
		case <-done:
			fmt.Println("Done!")
			return
		case t := <-ticker.C:
			fmt.Println("Current time: ", t)
		}
	}
}
