JavaScript

const ms = Date.now();
const seconds = Math.floor(Date.now() / 1000);
const date = new Date(ms);

Python

import time, datetime
ms = int(time.time() * 1000)
seconds = int(time.time())
dt = datetime.datetime.fromtimestamp(seconds)

Java

long ms = System.currentTimeMillis();
long seconds = ms / 1000;
Instant instant = Instant.ofEpochMilli(ms);

PHP

$seconds = time();
$ms = (int) round(microtime(true) * 1000);
$date = date('Y-m-d H:i:s', $seconds);

Go

now := time.Now()
ms := now.UnixMilli()
seconds := now.Unix()
t := time.UnixMilli(ms)

C#

var now = DateTimeOffset.UtcNow;
long ms = now.ToUnixTimeMilliseconds();
long seconds = now.ToUnixTimeSeconds();
var dt = DateTimeOffset.FromUnixTimeMilliseconds(ms);

Ruby

seconds = Time.now.to_i
ms = (Time.now.to_f * 1000).to_i
time = Time.at(seconds)

Shell

date +%s
date +%s%3N
