Understanding Epoch Time
What is Epoch Time?
Epoch time, also known as Unix time or POSIX time, is the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970.
Why is it Used?
It's a simple, standardized way for computer systems to handle time. Since it's just a number, it's easy to store, compare, and calculate time differences without worrying about time zones, daylight saving, or different calendar systems.
Seconds vs. Milliseconds
While the strict definition of Unix time is in seconds, many systems (like JavaScript's `Date.now()`) use milliseconds to provide greater precision. This tool automatically detects whether your input is in seconds, milliseconds, or even microseconds.
