Epoch & Unix timestamp converter

An epoch, also known as a Unix timestamp, is a measure of the number of seconds that have elapsed since the start of the Unix epoch: midnight UTC of January 1, 1970. This system is commonly used in computer systems and other digital devices to keep track of time.

One of the key advantages of using epoch time is its simplicity. Because it is based on a single reference point, it is easy to calculate the number of seconds that have passed between any two given points in time. Additionally, epoch time is independent of time zones, so it can be used consistently across the world.

However, there are some limitations to using epoch time. For one, it does not account for leap seconds, which are occasionally added to keep UTC in sync with the Earth's rotation. As a result, the difference between epoch time and UTC can vary over time. Additionally, because it is based on a 32-bit integer, the maximum representable time in epoch format is limited to the year 2038.

Overall, epoch time is a simple and widely used system for representing and keeping track of time in computer systems and other digital devices. While it has some limitations, it is an important tool for working with time-related data.
