Look at the example code:

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())
}

Output result:

1423361979
2015-02-08 10:19:39 AM
08/02/2015 10:19:39 AM
