比较两个时间

日期字符串转日期

日期字符串转时间戳

时间戳转日期

时间戳转对应日期零时字符串

时间戳转对应日期实际字符串

给定日期字符串获取指定时间之后的日期

支持整体为年>月>日顺序的任意时间格式相比较，前提是输入的两个参数格式相同，可输入的格式有：

YYYYMMDD、YYYY-MM-DD、YYYY/MM/DD、YYYY:MM:DD HH:mm:ss、YYYY:MM:DD HH:mm、YYYY-MM-DD HH-mm、YYYYMM、YYYY、YYYY/MM/DD HH:mm:ss等等。。。

	fmt.Println("compare 20201001 and 20201001: ", lacia.CompareTwoStrTime("20201001", "20201001")) // 0
	fmt.Println("compare 20201002 and 20211001: ", lacia.CompareTwoStrTime("20201002", "20211001")) // 2
	fmt.Println("compare 20201102 and 20201001: ", lacia.CompareTwoStrTime("20201102", "20201001")) // 1
	fmt.Println("compare 202101 and 202010: ", lacia.CompareTwoStrTime("202101", "202010")) // 1
	fmt.Println("compare 2021 and 2020: ", lacia.CompareTwoStrTime("2021", "2020")) // 1
	fmt.Println("compare 2021-01-01 and 2020-12-01: ", lacia.CompareTwoStrTime("2021-01-01", "2020-12-01")) // 1
	fmt.Println("compare 2020-12-01 and 2021-12-01: ", lacia.CompareTwoStrTime("2020-12-01", "2021-12-01")) // 2

日期字符串转日期

	t1, errs := lacia.GetTimeByStr("2020-10-01")
	fmt.Println(t1,errs)  // 2020-10-01 00:00:00 +0000 UTC 
	t2, errs := lacia.GetTimeByStr("20201031")
	fmt.Println(t2,errs) // 2020-10-31 00:00:00 +0000 UTC 
	t5, errs := lacia.GetTimeByStr("202110a1") // error
	fmt.Println(t5,errs) // 0001-01-01 00:00:00 +0000 UTC input timeStr format error

日期字符串转时间戳

	s1, err := lacia.GetTsByTimeStr("2020-10-01 00:05:05")
	fmt.Println(s1, err) //1601481905 
	s2, err := lacia.GetTsByTimeStr("2020-10-00 00:05:05")
	fmt.Println(s2, err) //-1 parsing time "2020-10-00 00:05:05": day out of range

时间戳转日期

	tm := lacia.GetTimeByTs(1602133570)
	fmt.Println(tm) //2020-10-08 13:06:10 +0800 CST
	tm = lacia.GetTimeByTs(1602086400)
	fmt.Println(tm) //2020-10-08 00:00:00 +0800 CST

时间戳转对应日期零时字符串

	fmt.Println(lacia.GetTimeStrOfDayZeroByTs(1602133570)) // 2020-10-08 00:00:00
	fmt.Println(lacia.GetTimeStrOfDayZeroByTs(1601481600)) // 2020-10-01 00:00:00

时间戳转对应日期实际字符串

fmt.Println(lacia.GetTimeStrOfDayTimeByTs(1602133570)) //2020-10-08 13:06:10
fmt.Println(lacia.GetTimeStrOfDayTimeByTs(1602086400)) //2020-10-08 00:00:00

给定日期字符串获取指定时间之后的日期

	fmt.Println(lacia.GetPreferTimeByTimeStrAndDifference("20201001", 0, 1, 0))   // 2020-11-01 00:00:00 +0000 UTC 
	fmt.Println(lacia.GetPreferTimeByTimeStrAndDifference("20201001", 0, 0, 5))   //2020-10-06 00:00:00 +0000 UTC 
	fmt.Println(lacia.GetPreferTimeByTimeStrAndDifference("20201001", 0, 2, 1))   // 2020-12-02 00:00:00 +0000 UTC 
	fmt.Println(lacia.GetPreferTimeByTimeStrAndDifference("20201001", 0, 3, 0))   // 2021-01-01 00:00:00 +0000 UTC 
	fmt.Println(lacia.GetPreferTimeByTimeStrAndDifference("20201001", 0, -1, 0))  // 2020-09-01 00:00:00 +0000 UTC 
	fmt.Println(lacia.GetPreferTimeByTimeStrAndDifference("20201001", 0, -1, -1)) //2020-08-31 00:00:00 +0000 UTC
