In the world of data science and programming, managing time series data is paramount. Often, data imported from databases, APIs, or legacy systems utilizes the UNIX timestamp format—a simple, integer representation of time that is highly efficient for machines but completely opaque to humans. A UNIX timestamp calculates the total number of seconds that have
