Golang : Get file last modified date and time

In this tutorial, we will learn how to get a file last modified date and time with Go. Getting the last modified date and time is fairly straight forward. We will just extract the information via http://golang.org/pkg/os/#FileInfo

We will test the code with a make up binary.file with the following information

 localhost:~ admin$ ls -la binary.file
 -rwxr-xr-x  1 admin  staff  2206048 Feb 12 22:00 binary.file

and this the Go code to retrieve the last modified date and time information from the binary.file

gettime.go

 package main

 import (
 "fmt"
 "os"
 )


 func main() {

 filename := "binary.file"

 // get last modified time
 file, err := os.Stat(filename)

 if err != nil {
 fmt.Println(err)
 }

 modifiedtime := file.ModTime()

 fmt.Println("Last modified time : ", modifiedtime)
 }

Execute the code above and this will be output :

 go run gettime.go
 Last modified time :  2014-02-12 22:00:18 +0800 MYT

Hope this tutorial can be useful to you.
