About Epoch/Unix Timestamps

The Unix epoch is 00:00:00 UTC on January 1, 1970. Epoch time counts the number of seconds (or milliseconds) that have elapsed since this reference point. This system is widely used in computing because it provides a standardized way to represent time across different systems and programming languages.

Getting Current Epoch Time

JavaScript/Node.js

Math.floor(Date.now() / 1000) // seconds
Date.now() // milliseconds

Python

import time
int(time.time()) # seconds
int(time.time() * 1000) # milliseconds

Java

// Java 8+<br/>
            Instant.now().getEpochSecond() // seconds<br/>
            System.currentTimeMillis() // milliseconds

C#

DateTimeOffset.Now.ToUnixTimeSeconds() // seconds<br/>
            DateTimeOffset.Now.ToUnixTimeMilliseconds() // milliseconds

Converting Date to Epoch

PHP

strtotime("2023-01-15 12:00:00") // seconds<br/>
            $date = new DateTime("2023-01-15 12:00:00");<br/>
            $date->format(&lsquo;U&lsquo;) * 1000 // milliseconds

SQL (MySQL)

SELECT UNIX_TIMESTAMP(‘2023-01-15 12:00:00‘);
SELECT UNIX_TIMESTAMP(‘2023-01-15 12:00:00‘) * 1000;

Go

t, _ := time.Parse(&ldquo;2006-01-02 15:04:05&ldquo;,&ldquo;2023-01-15 12:00:00&ldquo;)<br/>
            t.Unix() // seconds<br/>
            t.UnixMilli() // milliseconds

Shell

date -d“2023-01-15 12:00:00“+%s # seconds
date -d“2023-01-15 12:00:00“+%s%3N # milliseconds

Converting Epoch to Date

JavaScript

// Seconds to Date<br/>
            new Date(1673784000 * 1000).toISOString()<br/><br/>
            // Milliseconds to Date<br/>
            new Date(1673784000000).toISOString()

Python

from datetime import datetime
datetime.fromtimestamp(1673784000) # seconds
datetime.fromtimestamp(1673784000000 / 1000) # milliseconds

C++

#include <chrono>
#include <ctime>
std::time_t time = 1673784000;
std::tm *tm = std::localtime(&time);

PowerShell

[datetimeoffset]::
FromUnixTimeSeconds(1673784000)
FromUnixTimeMilliseconds(1673784000000)

Why Use Epoch Time?

Standardized time representation across different systems and timezones
Easier for calculations and comparisons than human-readable dates
Compact storage format in databases and APIs
Essential for logging, caching, and scheduling systems

Common Use Cases

API responses and request timestamps
Database record timestamps
Log file entries
Cache expiration headers
Session timeouts
Performance measurement
