विभिन्न प्रोग्रामिंग भाषाओं में वर्तमान यूनिक्स समय कैसे प्राप्त करें?

import time
# Get the current timestamp
current_timestamp = int(time.time())

// get the current timestamp
var currentTimestamp = Math.floor(Date.now() / 1000);

long currentTimestamp = System.currentTimeMillis() / 1000;

long currentTimestamp = DateTimeOffset.UtcNow.ToUnixTimeSeconds();

#include <iostream>
#include <chrono>
int main() {
auto now = std::chrono::system_clock::now();
auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);
auto epoch = now_ms.time_since_epoch();
auto value = std::chrono::duration_cast<std::chrono::seconds>(epoch);
std::cout << value.count() << std::endl;
return 0;
}

<?php
$currentTimestamp = time();
echo $currentTimestamp;
?>

const currentTimestamp = Math.floor(Date.now() / 1000);

let currentTimestamp = Int(Date().timeIntervalSince1970)

current_timestamp = Time.now.to_i

package main
import (

func main() {
currentTimestamp := time.Now().Unix()
fmt.Println(currentTimestamp)
}
