A Unix Timestamp is a way to track time in computing, representing the number of seconds that have elapsed since the start of the Unix epoch on January 1, 1970, at 00:00:00 UTC. This system is widely used in programming and databases to handle date and time in a consistent manner. Unix Timestamps are useful because they provide a simple, numeric format that is easy to store and manipulate. They can be converted to human-readable dates and times in various programming languages, making them essential for applications that require precise timekeeping, such as logging events or scheduling tasks.
