Golang : Convert Unix timestamp to UTC timestamp

Problem :

You have a Unix timestamp and you want to convert it to UTC time format. How to do that in Golang?

For example :

>date +%s

1432572732

Solution :

Use the strconv.ParseInt() function to convert unix time stamp to integer value first and then use time.Unix() to convert the integer value to proper UTC (Coordinated Universal Time) time stamp.

Here you go:

 package main

 import (
  "fmt"
  "os"
  "strconv"
  "time"
 )

 func main() {

  unixTimeStamp := "1432572732"

  unixIntValue, err := strconv.ParseInt(unixTimeStamp, 10, 64)

  if err != nil {
 fmt.Println(err)
 os.Exit(1)
  }

  timeStamp := time.Unix(unixIntValue, 0)

  fmt.Println(timeStamp)
 }

Output :

2015-05-25 16:52:12 +0000 UTC
