Developer Code Examples

Ready-to-use code snippets for timestamp conversion in popular languages

JavaScript

new Date().getTime() // Current timestamp in milliseconds
Math.floor(Date.now() / 1000) // Current timestamp in seconds
new Date(timestamp * 1000) // Convert seconds to Date object
date.toISOString() // Convert to ISO 8601 format

Python

import time; time.time() # Current timestamp
datetime.datetime.utcfromtimestamp(ts) # Convert timestamp
datetime.datetime.now().timestamp() # Get timestamp
dt.strftime("%Y-%m-%d %H:%M:%S") # Format datetime

PHP

time() // Current Unix timestamp
date("Y-m-d H:i:s", $timestamp) // Format timestamp
strtotime("2021-01-01") // Convert string to timestamp
DateTime::createFromFormat("U", $timestamp) // Create DateTime

Java

System.currentTimeMillis() / 1000 // Current timestamp
Instant.ofEpochSecond(timestamp) // Convert timestamp
LocalDateTime.ofInstant(instant, ZoneId.systemDefault()) // To LocalDateTime
DateTimeFormatter.ISO_LOCAL_DATE_TIME.format(dateTime) // Format

Frequently Asked Questions

Common questions about Unix timestamps and conversion

What is a Unix timestamp and how does it work?

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch). It provides a universal way to represent time across different systems and programming languages, making it ideal for databases, APIs, and system logs.

What's the difference between seconds and milliseconds timestamps?

Seconds timestamps (10 digits) are the standard Unix format, while milliseconds timestamps (13 digits) provide higher precision. JavaScript uses milliseconds by default, while most other systems use seconds. Our converter automatically detects and handles both formats.

How do I convert timestamps across different timezones?

Unix timestamps are always in UTC, but our converter displays the equivalent time in any timezone you select. We handle daylight saving time transitions automatically and support all global timezone regions for accurate conversions.

Is my timestamp data secure when using this converter?

Absolutely. All timestamp conversions are performed locally in your browser. No data is transmitted to our servers, ensuring complete privacy and security for your timestamp data and sensitive information.
