Нэг секундын турш үргэлжлэх, хуваалцах боломжтой хуудас. URL-г захидал эсвэл ярианд байрлуулвал бусад хүн UTC, өөрийн цаг бүс, бусад нийтлэг форматаар харуулсан яг ижил секундыг харах болно. "Хэн нь ямар цаг бүсэд байсан" гэсэн эргэлт байхгүй.

Өөрийн цаг бүс: JavaScript-ийг идэвхжүүлэх

Энэ утга кодонд үүсгэнэ

Python

from datetime import datetime, timezone

now = datetime.now(timezone.utc)
print(now.isoformat())          # 2026-01-01T12:00:00+00:00
print(int(now.timestamp()))     # unix seconds

JavaScript

const now = new Date();
console.log(now.toISOString());   // 2026-01-01T12:00:00.000Z
console.log(Date.now());          // unix milliseconds
console.log(Math.floor(Date.now() / 1000)); // unix seconds

Go

package main

import (
	"fmt"
	"time"
)

func main() {
	now := time.Now().UTC()
	fmt.Println(now.Format(time.RFC3339)) // 2026-01-01T12:00:00Z
	fmt.Println(now.Unix())               // unix seconds
}

Java

import java.time.Instant;

Instant now = Instant.now();            // always UTC
System.out.println(now);                // 2026-01-01T12:00:00Z
System.out.println(now.getEpochSecond());

C#

var now = DateTimeOffset.UtcNow;
Console.WriteLine(now.ToString("o"));            // ISO 8601 round-trip
Console.WriteLine(now.ToUnixTimeSeconds());
Console.WriteLine(now.ToUnixTimeMilliseconds());

Rust

// chrono = "0.4"
use chrono::Utc;

let now = Utc::now();
println!("{}", now.to_rfc3339());   // 2026-01-01T12:00:00+00:00
println!("{}", now.timestamp());    // unix seconds
