Frequently Asked Questions

What is a Unix epoch timestamp?
A Unix timestamp (epoch time) represents the total number of seconds (or milliseconds) that have elapsed since midnight Coordinated Universal Time (UTC) on January 1, 1970, not counting leap seconds.
How does this tool distinguish between seconds and milliseconds timestamps?
Timestamps with 10 digits (around 1.7 billion) are automatically detected as seconds, while 13-digit numbers are treated as milliseconds, 16 digits as microseconds, and 19 digits as nanoseconds.
What is the Year 2038 Problem (Y2038)?
On January 19, 2038 at 03:14:07 UTC, 32-bit signed integers reach their maximum value (2,147,483,647) and overflow into negative numbers (-2,147,483,648). Modern 64-bit systems resolve this with 64-bit integers valid for billions of years.
Can I calculate future or past timestamps with offsets?
Yes! The "Timestamp Offset & Math" tab allows you to easily add or subtract minutes, hours, days, weeks, or months from any Unix timestamp or the current time.
