What is a Unix timestamp (Epoch time)?

A Unix timestamp is the total number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC (not counting leap seconds). It is widely used in databases, operating systems, and computer APIs worldwide.

What is the difference between 10-digit and 13-digit timestamps?

A 10-digit timestamp measures time in seconds (standard Unix/Linux/PHP/Python), while a 13-digit timestamp measures time in milliseconds (standard in JavaScript Date.now() and Java).

What is the Year 2038 Problem (Y2K38)?

On January 19, 2038 at 03:14:07 UTC, 32-bit signed integers will overflow past 2,147,483,647 into negative numbers. Modern 64-bit systems are immune and safe for over 290 billion years.

💡 Pro-Tip: Standard Unix timestamps are 10 digits (seconds since Jan 1, 1970). JavaScript timestamps (`Date.now()`) use 13 digits (milliseconds). This tool auto-detects both seamlessly.

The Year 2038 Problem (Y2K38)

On January 19, 2038 at 03:14:07 UTC, the 32-bit signed integer used by legacy systems will overflow past 2,147,483,647 into negative numbers, wrapping back to 1901. Modern 64-bit systems will not run out of timestamps for another 292 billion years!
