Code Examples

Python

from datetime import datetime, timezone

# Convert epoch 1100000000 to UTC datetime
dt = datetime.fromtimestamp(1100000000, tz=timezone.utc)
print(dt)  # 2004-11-09T11:33:20+00:00

# Format as human-readable string
print(dt.strftime("%A, %B %d, %Y %H:%M:%S UTC"))
# Tuesday, November 9, 2004, 11:33:20 UTC

JavaScript

// Convert epoch 1100000000 to Date
const date = new Date(1100000000 * 1000);
console.log(date.toISOString());  // 2004-11-09T11:33:20Z
console.log(date.toUTCString());  // Tue, 09 Nov 2004 11:33:20 GMT

// Get individual components
console.log(date.getUTCFullYear());  // 2004
console.log(date.getUTCMonth() + 1); // 11

Go

package main

import (
    "fmt"
    "time"
)

func main() {
    t := time.Unix(1100000000, 0).UTC()
    fmt.Println(t.Format(time.RFC3339)) // 2004-11-09T11:33:20Z
    fmt.Println(t.Weekday())            // Tuesday
}
