How to parse unix timestamp to time.Time

I'm trying to parse an Unix timestamp but I get out of range error. That doesn't really makes sense to me, because the layout is correct (as in the Go docs):

package main

import "fmt"
import "time"

func main() {
    tm, err := time.Parse("1136239445", "1405544146")
    if err != nil{
        panic(err)
    }

    fmt.Println(tm)
}

Playground

The time.Parse function does not do Unix timestamps. Instead you can use strconv.ParseInt to parse the string to int64 and create the timestamp with time.Unix:

package main

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

func main() {
    i, err := strconv.ParseInt("1405544146", 10, 64)
    if err != nil {
        panic(err)
    }
    tm := time.Unix(i, 0)
    fmt.Println(tm)
}

Output:

2014-07-16 20:55:46 +0000 UTC

Edit:

Changed from strconv.Atoi to strconv.ParseInt to avoid int overflows on 32 bit systems.
