time 时间戳与格式化

package main

 

import (

"fmt"

"time"

)

 

func main() {

//获取时间戳

timestamp := time.Now().Unix()

fmt.Println(timestamp)

 

//格式化为字符串,tm为Time类型

tm := time.Unix(timestamp, 0)

fmt.Println(tm.Format("2006-01-02 03:04:05 PM"))

fmt.Println(tm.Format("02/01/2006 15:04:05 PM"))

 

 

//从字符串转为时间戳，第一个参数是格式，第二个是要转换的时间字符串

tm2, _ := time.Parse("01/02/2006", "02/08/2015")

fmt.Println(tm2.Unix())

}

格式字符串的时候，用的是2006-01-02这种格式。其实在Go语言里，这些数字都是有特殊函义的，不是随便指定的数字，见下面列表：

月份 1,01,Jan,January

日　 2,02,_2

时　 3,03,15,PM,pm,AM,am

分　 4,04

秒　 5,05

年　 06,2006

周几 Mon,Monday

时区时差表示 -07,-0700,Z0700,Z07:00,-07:00,MST

时区字母缩写 MST
