What is a Unix Timestamp?
A Unix timestamp (also known as Epoch time, POSIX time, or Unix Epoch) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. This date is known as the "Unix Epoch."
Unix timestamps are widely used because they:
- Are timezone-independent - The same number represents the same moment everywhere
- Are easy to store - A single integer instead of formatted date strings
- Allow easy calculations - Add/subtract seconds to shift time
- Sort naturally - Higher numbers are later dates
