About Unix Epoch Time

What is Epoch Time?

The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).

Seconds vs Milliseconds

A 10-digit timestamp typically represents seconds, extending to the year 2286. A 13-digit timestamp represents milliseconds, providing more precise timing commonly used in JavaScript and Java.

The Year 2038 Problem

On January 19, 2038, the 32-bit signed integer used to store Unix time will overflow, returning to a negative value. Modern systems use 64-bit integers to avoid this issue, extending the range for billions of years.
