格式化字符串为时间学习总结

package main

import (
	"fmt"
	"time"
)

func main() {
	test, err := time.Parse("2006-01-02", "2013-01-12")
	if err != nil {
		panic(err)
	}

	fmt.Println(test)
}

[ `run` | done: 4.533945ms ]
2013-01-12 00:00:00 +0000 UTC

其中time.parse格式改变后，未发生变化

test, err := time.Parse("2006/01/02", "2013/01/12")

[ `run` | done: 1.499388ms ]
2013-01-12 00:00:00 +0000 UTC

再换，结果未变：

test, err := time.Parse("01/02/2006", "01/12/2013")

[ `run` | done: 1.471152ms ]
2013-01-12 00:00:00 +0000 UTC

截取取小时:

test, err := time.Parse("2006-01-02 15", "2013-05-13 13")

截取到分钟：

test, err := time.Parse("2006-01-02 15:04", "2013-05-13 10:30")

[ `run` | done: 1.414665ms ]
2013-05-13 10:30:00 +0000 UTC

截取到秒:

 

test, err := time.Parse("2006-01-02 15:04:05", "2013-05-13 10:30:03")

[ `run` | done: 1.554238ms ]
2013-05-13 10:30:03 +0000 UTC

 

随着截取位置的不同，通过补零设置
