1.获取当前时间,返回UTC时间

    currentTime := time.Now()
	fmt.Printf("%v : %T\n", currentTime, currentTime)

2.获取当前时间戳

    timeUnix := time.Now().Unix() //单位秒
	fmt.Printf("%v : %T\n", timeUnix, timeUnix)
	timeUnixNano := time.Now().UnixNano() //单位纳秒
	fmt.Printf("%v : %T\n", timeUnixNano, timeUnixNano)

3.UTC时间格式化输出

	timeStr := currentTime.Format("2006-01-02 15:04:05")
	fmt.Printf("%v : %T\n", timeStr, timeStr)
	//可以指定时区，""代表UTC时间
	local, err := time.LoadLocation("")
	timeLocalStr := currentTime.In(local).Format("2006-01-02 15:04:05")
	fmt.Printf("%v : %T\n", timeLocalStr, timeLocalStr)

4.时间字符串转UTC时间

	formatTimeStr := "2018-01-03 10:11:12"
	formatTime, err := time.Parse("2006-01-02 15:04:05", formatTimeStr)
	if err == nil {
		fmt.Printf("%v : %T\n", formatTime, formatTime)
	}
	//指定时区
	loc, err := time.LoadLocation("Local")
	formatLocalTime , err := time.ParseInLocation("2006-01-02 15:04:05", formatTimeStr, loc)
	if err == nil {
		fmt.Printf("%v : %T\n", formatLocalTime, formatLocalTime)
	}

5.时间戳转时间字符串

	formatTimeStr2 := time.Unix(timeUnix, 0).Format("2006-01-02 15:04:05")
	fmt.Printf("%v : %T\n", formatTimeStr2, formatTimeStr2)

6.字符串转时间戳

	formatTime2, _ := time.Parse("2006-01-02 15:04:05", formatTimeStr)
	timeUnix2 := formatTime2.Unix()
	fmt.Printf("%v : %T\n", timeUnix2, timeUnix2)
