❓ Frequently Asked Questions

What is an epoch timestamp?

An epoch timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 00:00:00 UTC, also known as the Unix epoch.

Why use epoch timestamps?

Epoch timestamps are universal, timezone-independent, and easy to perform calculations with. They’re the standard for most programming languages and databases.

What’s the difference between seconds and milliseconds?

Seconds timestamps are standard Unix timestamps, while milliseconds provide millisecond precision (1000x more precise). JavaScript uses milliseconds by default.

How do I handle timezones?

Always store timestamps in UTC, then convert to local time for display. Our converter handles timezone conversion automatically.

What’s the maximum timestamp value?

For 32-bit systems, the maximum is January 19, 2038 (Year 2038 problem). For 64-bit systems, it’s the year 2262.

Can I convert negative timestamps?

Yes! Negative timestamps represent dates before 1970. Our converter handles the full range of valid timestamps.

How accurate are the conversions?

Our converter provides nanosecond precision for maximum accuracy. All calculations use precise astronomical algorithms.

🛠️ Integration Examples

JavaScript/Node.js

// Convert current timestamp to date
const timestamp = Date.now(); // milliseconds
const date = new Date(timestamp);
console.log(date.toISOString()); // ISO 8601 format
 
// Convert date to timestamp
const dateString = "2024-01-01T00:00:00Z";
const timestamp = new Date(dateString).getTime();

Python

import time
from datetime import datetime
 
# Current timestamp
timestamp = int(time.time())  # seconds
print(f"Current timestamp: {timestamp}")
 
# Convert timestamp to date
date = datetime.fromtimestamp(timestamp)
print(f"Date: {date.isoformat()}")

SQL Database

-- Convert timestamp to date
SELECT 
    FROM_UNIXTIME(timestamp_column) as readable_date,
    UNIX_TIMESTAMP() as current_timestamp
FROM your_table;
 
-- Convert date to timestamp
SELECT UNIX_TIMESTAMP('2024-01-01 00:00:00') as timestamp;

📚 Understanding Epoch Time

Historical Context

The Unix epoch (January 1, 1970) was chosen as a reference point because:

  • It was a logical starting point for computer systems
  • It provided a clean, round number for calculations
  • It was before most modern computing began

Technical Benefits

  • Universal Standard - Same reference point worldwide
  • Easy Calculations - Simple arithmetic for time differences
  • No Timezone Issues - Always in UTC
  • Compact Storage - Single integer value
  • Sortable - Natural numerical ordering

Common Applications

  • Log Files - Record when events occurred
  • API Responses - Return consistent timestamp format
  • Database Records - Store creation/modification times
  • Cache Expiration - Set time-based cache invalidation
  • Scheduling - Plan future events and tasks

🚀 Pro Tip: Bookmark this epoch converter for quick timestamp conversions during development. It’s essential for any developer working with dates and times!
