Unix Timestamps Across the Languages

README.md

Because every language does this a little differently, here's a collection of ways to compute the unix timestamp. The technical details of what that means can be read on Wikipedia.

epoch.exs

# Elixir/Erlang R18+
:os.system_time(:seconds)
# Older
{megasec, sec, _microsec} = :os.timestamp
megasec * 1000000 + sec

epoch.go

package main
import "time"
func main() {
  time.Now().Unix()
}

epoch.js

/* JavaScript */
Math.round(Date.now() / 1000)

epoch.php

<?php
# PHP
time()

epoch.py

# Python
import calendar
import time
calendar.timegm(time.localtime())

epoch.rb

# Ruby
Time.now.to_i

epoch.sh

#!/bin/bash
# shell script
date "+%s"
