What is a Unix Timestamp?
A timestamp is a numerical representation of a specific point in time, recording when an event occurred within a computer system. Unlike human-readable dates, timestamps provide an objective, machine-processable record that's independent of time zones and locale settings.

The most common format is the Unix timestamp—the number of seconds elapsed since the Unix Epoch (January 1, 1970, 00:00:00 UTC). This standardized reference point enables consistent time representation across different systems and programming languages. Alternatively, some systems use milliseconds since epoch for higher precision in time-sensitive applications.

Common Use Cases
    • Data Versioning: Track when files were created or modified, enabling version control and rollback capabilities.
    • Log Analysis: Reconstruct event sequences for debugging, security audits, and system monitoring.
    • Resource Management: Determine the order of operations when multiple processes access shared resources.
    • Distributed Systems: Synchronize events across servers and maintain consistency in distributed databases.

Common Timestamp Formats
    • Unix timestamps (seconds since epoch): 1234567890
    • ISO 8601: 2024-01-31T12:00:00Z (human-readable)
    • Milliseconds since epoch: 1234567890000 (high precision)

Legacy systems that store Unix timestamps as signed 32-bit integers face a critical limitation: the maximum representable value is 2,147,483,647, corresponding to January 19, 2038, at 03:14:07 UTC. Beyond this point, timestamps will overflow, potentially causing system failures.

To prevent disruptions, systems must migrate to 64-bit timestamp representations, which extend the viable range by billions of years. For more information, see theYear 2038 Problem article on Wikipedia.
