Gumawa ng halaga na ito sa code
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
