Processed on our server. What you enter is sent over an encrypted connection, calculated, and returned. It is never written to a database or logged, and nothing is retained once the result is sent. Avoid entering passwords, API keys or other secrets. How we handle data

Epoch Time Explained

Unix epoch time counts seconds from January 1, 1970, 00:00:00 UTC. It is the universal language of time in computing — databases store it, APIs return it, logs record it. This tool translates it back to human-readable form instantly.

Timezone-Aware

A Unix timestamp represents a universal moment in time. The same timestamp shows different clock times depending on timezone. Select your timezone to see the local equivalent of any epoch value.

Knowledge Base

Working with Unix Timestamps in Development Methodology.

Unix timestamps appear everywhere in software: JWT tokens use exp and iat fields, database records store created_at as integer timestamps, webhook payloads include event times as epoch values, and server logs record every request as a Unix timestamp.

The Calculation Branch

Unix Timestamp = (Date − Jan 1, 1970 UTC) in seconds | Date = Unix Epoch + timestamp seconds

Industrial Standards.

Conversion uses PHP's Carbon library, which handles timezone offset, daylight saving time transitions, and leap years correctly. The ISO 8601 output includes timezone offset for unambiguous cross-system communication.

In-Depth Analysis & Reference Data

Common Unix timestamp milestones: 0 = Jan 1, 1970 (Unix epoch); 1,000,000,000 = Sep 9, 2001; 1,234,567,890 = Feb 13, 2009 (celebrated by programmers); 2,000,000,000 = May 18, 2033 (upcoming). The Year 2038 Problem: 32-bit systems store timestamps as signed integers, which overflow at 2,147,483,647 (Jan 19, 2038). Modern 64-bit systems are not affected.

Registry Questions & FAQ.

What is the difference between Unix timestamp in seconds vs milliseconds?

Unix timestamps are traditionally in seconds (10 digits in 2025). JavaScript and many modern APIs use milliseconds (13 digits). If you paste a 13-digit timestamp and get a date far in the future, divide by 1000 first. For example: 1700000000000ms = 1700000000s = Nov 14, 2023.

How to get a Unix timestamp in different programming languages?

PHP: time() | Python: import time; time.time() | JavaScript: Date.now()/1000 | Go: time.Now().Unix() | SQL (MySQL): UNIX_TIMESTAMP() | SQL (PostgreSQL): EXTRACT(EPOCH FROM NOW()) | Bash: date +%s
