Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 (midnight UTC), also known as the Unix epoch. It's widely used in programming.
What's the difference between Unix seconds and milliseconds?
Unix seconds (10 digits, e.g., 1710000000) count seconds since epoch. Milliseconds (13 digits) provide more precision, commonly used in JavaScript and Java.
What is the Year 2038 problem?
32-bit systems store Unix timestamps as signed 32-bit integers, which will overflow on January 19, 2038. 64-bit systems are not affected.
