About Unix Timestamps

What is a Unix Timestamp?

A Unix timestamp (also known as Epoch time, POSIX time, or Unix time) is a system for representing a point in time as a single number: the number of seconds that have elapsed since the Unix Epoch - January 1, 1970, 00:00:00 UTC - not counting leap seconds.

Common Uses

Unix timestamps are widely used in computing because:

They are language and platform independent
They simplify date/time arithmetic (adding and subtracting times)
They are compact and efficient for storage
They enable easy sorting and comparison of dates

Timestamp Units

While the standard Unix timestamp is in seconds, variations include:

Milliseconds: 1,000 times larger than a second-based timestamp (used in JavaScript's Date.now())
Microseconds: 1,000,000 times larger than a second-based timestamp
Nanoseconds: 1,000,000,000 times larger than a second-based timestamp

Limitations

32-bit systems using signed integers for Unix time will experience the "Year 2038 problem" on January 19, 2038, when the timestamp will exceed the largest value that can be represented in a 32-bit signed integer. Modern 64-bit systems can represent dates far beyond human timescales.
