Fork了别人一个Repository 日期解析

这个package的功能很简单就是将一个未知的日期格式转化为标准的日期格式，日常生活中可以作为日期的数据清洗，接下来将开发以此Repository为基础，支持可配置的自动识别日期格式的功能，Repository正在开发中，有兴趣的小伙伴可以随时提PR，共同完善，共同学习。

Repository地址: noaway/dateparse

具体的使用方式如下：

package main import (	"flag"	"fmt"	"time"	"github.com/apcera/termtables"	"github.com/noaway/dateparse" ) // _ _ // | | | | // __| | __ _ | |_ ___ _ __ __ _ _ __ ___ ___ // / _` | / _` | | __| / _ \ | '_ \ / _` | | '__| / __| / _ \ // | (_| | | (_| | | |_ | __/ | |_) | | (_| | | | \__ \ | __/ // \__,_| \__,_| \__| \___| | .__/ \__,_| |_| |___/ \___| // | | // |_| var examples = []string{	"May 8, 2009 5:57:51 PM",	"Nov 8, 2017",	"Mon Jan 2 15:04:05 2006",	"Mon Jan 2 15:04:05 MST 2006",	"Mon Jan 02 15:04:05 -0700 2006",	"Monday, 02-Jan-06 15:04:05 MST",	"Mon, 02 Jan 2006 15:04:05 MST",	"Tue, 11 Jul 2017 16:28:13 +0200 (CEST)",	"Mon, 02 Jan 2006 15:04:05 -0700",	"Mon Aug 10 15:44:11 UTC+0100 2015",	"Fri Jul 03 2015 18:04:07 GMT+0100 (GMT Daylight Time)",	"12 Feb 2006, 19:17",	"2013-Feb-03",	// mm/dd/yy	"3/31/2014",	"03/31/2014",	"08/21/71",	"8/1/71",	"4/8/2014 22:05",	"04/08/2014 22:05",	"04/2/2014 03:00:51",	"8/8/1965 12:00:00 AM",	"8/8/1965 01:00:01 PM",	"8/8/1965 01:00 PM",	"8/8/1965 1:00 PM",	"8/8/1965 12:00 AM",	"4/02/2014 03:00:51",	"03/19/2012 10:11:59",	"03/19/2012 10:11:59.3186369",	// yyyy/mm/dd	"2014/3/31",	"2014/03/31",	"2014/4/8 22:05",	"2014/04/08 22:05",	"2014/04/2 03:00:51",	"2014/4/02 03:00:51",	"2012/03/19 10:11:59",	"2012/03/19 10:11:59.3186369",	// yyyy-mm-ddThh	"2006-01-02T15:04:05+0000",	"2009-08-12T22:15:09-07:00",	"2009-08-12T22:15:09",	"2009-08-12T22:15:09Z",	// yyyy-mm-dd hh:mm:ss	"2014-04-26 17:24:37.3186369",	"2012-08-03 18:31:59.257000000",	"2014-04-26 17:24:37.123",	"2013-04-01 22:43:22",	"2014-12-16 06:20:00 UTC",	"2014-12-16 06:20:00 GMT",	"2014-04-26 05:24:37 PM",	"2014-04-26 13:13:43 +0800",	"2014-04-26 13:13:44 +09:00",	"2012-08-03 18:31:59.257000000 +0000 UTC",	"2015-09-30 18:48:56.35272715 +0000 UTC",	"2015-02-18 00:12:00 +0000 GMT",	"2015-02-18 00:12:00 +0000 UTC",	"2017-07-19 03:21:51+00:00",	"2014-04-26",	"2014-04",	"2014",	"2014-05-11 08:20:13,787",	// yyyymmdd and similar	"20140601",	// unix seconds, ms	"1332151919",	"1384216367189",	// Chinese date	"2017年11月09日",	"2017年11月01日 09:41",	// How long ago	"1 day ago",	"19 hours ago",	"26 minutes ago", } var (	timezone = "" ) func main() {	flag.StringVar(&timezone, "timezone", "UTC", "Timezone aka `America/Los_Angeles` formatted time-zone")	flag.Parse()	if timezone != "" {	// NOTE: This is very, very important to understand	// time-parsing in go	loc, err := time.LoadLocation(timezone)	if err != nil {	panic(err.Error())	}	time.Local = loc	}	table := termtables.CreateTable()	table.AddHeaders("Input", "Parsed, and Output as %v")	for _, dateExample := range examples {	// t, err := dateparse.ParseLocal(dateExample)	t, err := dateparse.ParseAny(dateExample)	if err != nil {	panic(err.Error())	}	table.AddRow(dateExample, fmt.Sprintf("%v", t))	}	fmt.Println(table.Render()) }
