Unix Time is a system for tracking time that counts the number of seconds that have passed since midnight on January 1, 1970, in the UTC time zone. This date is known as the "epoch." Unix Time does not account for leap seconds, making it a straightforward way to represent time in computing. It is widely used in various operating systems, including Linux and macOS, as well as in programming languages like Python and Java. Unix Time simplifies time calculations and comparisons, making it easier for developers to manage timestamps in applications and databases.
