What is a Unix Timestamp?
The Unix epoch (or Unix time/POSIX time) is a system for describing a point in time. It is defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970, minus leap seconds. Every day is treated as if it contains exactly 86400 seconds.
It is widely used in Unix-like and many other operating systems and file formats to efficiently track time without worrying about timezones or daylight saving time.
The Year 2038 Problem
If you're using a 32-bit signed integer to store a Unix timestamp, the maximum value it can hold is 2,147,483,647. This value will be reached on January 19, 2038, at 03:14:07 UTC. At that moment, older 32-bit systems will encounter an integer overflow, causing the time to wrap around to a negative number (December 13, 1901), potentially causing widespread software failures.
