Kwa muda wako mwenyewe: kuwezesha JavaScript kuona hili

Toa thamani hii katika mfumo wa sheria

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
