A Unix timestamp is a way to track time as a running total of seconds. It represents the number of seconds that have elapsed since the Unix Epoch (January 1, 1970 at midnight UTC).

Standard Unix time is recorded in seconds. However, modern environments like JavaScript (Date.now()) often track time in milliseconds (1/1000th of a second). Our tool supports both formats natively.
