Common Timestamps
What is a Unix Timestamp?
A Unix timestamp (also known as Epoch time or POSIX time) is a way of tracking time as a running total of seconds. It counts the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC (the Unix Epoch), not counting leap seconds.
Unix timestamps are widely used in computer systems and programming because they provide a simple, timezone-independent way to represent a specific point in time. They're commonly used in databases, APIs, log files, and many other applications.

What's the difference between seconds and milliseconds timestamps?
Unix timestamps in seconds are 10 digits (e.g., 1703980800), while millisecond timestamps are 13 digits (e.g., 1703980800000). Our converter automatically detects which format you're using.
What is the Year 2038 problem?
32-bit systems store timestamps as signed 32-bit integers, which will overflow on January 19, 2038. Most modern systems now use 64-bit timestamps, which won't overflow for billions of years.
Are timestamps affected by leap seconds?
Unix timestamps do not count leap seconds. Each day is assumed to have exactly 86,400 seconds. This means Unix time occasionally drifts from UTC, but the difference is minimal.
