What is a Unix timestamp?

A Unix timestamp (also known as epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent dates and times in programming, commonly used in APIs, databases, and server logs. This tool helps developers convert between Unix timestamps and human-readable date formats across multiple timezones.

Quick Tips

Seconds vs Milliseconds

Unix timestamps are typically measured in seconds (10 digits), but some systems like JavaScript use milliseconds (13 digits). This tool automatically detects which format you're using.

Getting Current Timestamp in Code

JavaScript: Math.floor(Date.now() / 1000)
Python: import time; int(time.time())
PHP: time()
Java: System.currentTimeMillis() / 1000

Common Timestamp Ranges

  • Timestamps starting with "16" → 2020-2021
  • Timestamps starting with "17" → 2023-2024
  • Timestamps starting with "18" → 2027-2028
  • Timestamps starting with "19" → 2030-2031

Common Use Cases

1. Convert API Response Timestamp

When you receive a Unix timestamp from an API (e.g., 1704412800), use this tool to see what date and time it represents in a human-readable format.

2. Calculate Days Until Event

Use the time difference calculator to find out exactly how many days, hours, and minutes remain until a specific timestamp (deadline, product launch, etc.).

3. Generate Timestamp for API Request

When you need to send a specific date/time in an API request, use the date picker to convert your desired date into a Unix timestamp that APIs expect.

4. Debug Server Logs

Server logs often include timestamps in Unix format. Paste the timestamp here to quickly understand when an event occurred in your local timezone.

Monitor API Reliability

Don't just calculate time, monitor your systems. ObserveOne checks your API health and uptime from multiple global locations.
