golang 基于时间比较 加上时区

golang 东八区时间字符串比较先转换为时间戳

timezone := time.FixedZone("CST", 8*3600)

	start, end := "2022-06-09 21:17:47", "2022-06-19 10:55:34"
	startTime, err := time.ParseInLocation(formatTime, start, timezone)
	if err != nil {
		panic(err)
	}

	endTime, _ := time.ParseInLocation(formatTime, end, timezone)
	if err != nil {
		panic(err)
	}

	nowTimestamp := time.Now().In(timezone).Unix()
	startTimestamp := startTime.Unix()
	endTimestamp := endTime.Unix()

然后基于时间戳比较

	fmt.Printf(" startTimestamp : %d \n endTimestamp : %d \n nowTimestamp : %d\n", startTimestamp, endTimestamp, nowTimestamp)
	
	if nowTimestamp < startTimestamp {
		fmt.Println(" 预约会议......")
	}

	if startTimestamp <= nowTimestamp && nowTimestamp <= endTimestamp {
		fmt.Println("进行中.......")
	}

	if endTimestamp < nowTimestamp {
		fmt.Println("历史会议.....")
	}

自带的after brofre

if startTime.After(nowTime) {
		fmt.Println(" 预约会议......")
	}

	if nowTime.After(startTime) && nowTime.Before(endTime) {
		fmt.Println("进行中.......")
	}

	if endTime.Before(nowTime) {
		fmt.Println("历史会议.....")
	}

	if startTime.After(nowTime) || (nowTime.After(startTime) && nowTime.Before(endTime)) {
		fmt.Println(" 非历史会议......")
	}
