Code Examples

Python

from datetime import datetime, timezone

# Convert epoch 1200000000 to UTC datetime
dt = datetime.fromtimestamp(1200000000, tz=timezone.utc)
print(dt)  # 2008-01-10T21:20:00+00:00

# Format as human-readable string
print(dt.strftime("%A, %B %d, %Y %H:%M:%S UTC"))
# Thursday, January 10, 2008, 21:20:00 UTC

JavaScript

// Convert epoch 1200000000 to Date
const date = new Date(1200000000 * 1000);
console.log(date.toISOString());  // 2008-01-10T21:20:00Z
console.log(date.toUTCString());  // Thu, 10 Jan 2008 21:20:00 GMT

// Get individual components
console.log(date.getUTCFullYear());  // 2008
console.log(date.getUTCMonth() + 1); // 1

Go

package main

import (
    "fmt"
    "time"
)

func main() {
    t := time.Unix(1200000000, 0).UTC()
    fmt.Println(t.Format(time.RFC3339)) // 2008-01-10T21:20:00Z
    fmt.Println(t.Weekday())            // Thursday
