Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp counts seconds since January 1, 1970 00:00:00 UTC (the Unix epoch). For example, 1700000000 = November 14, 2023 22:13:20 UTC. It provides a universal, timezone-independent way to represent time in computing.
How do I convert a Unix timestamp to a readable date?
Divide by 86,400 to get days since epoch, then calculate the date. In practice, use the converter or programming functions: JavaScript new Date(timestamp * 1000), Python datetime.fromtimestamp(ts).
What is the Year 2038 problem?
32-bit systems store Unix timestamps as signed integers, maxing out at 2,147,483,647 (January 19, 2038 03:14:07 UTC). After this, the value overflows to negative, causing date errors. 64-bit systems extend this to 292 billion years.
How do I get the current Unix timestamp?
In JavaScript: Math.floor(Date.now() / 1000). In Python: int(time.time()). In Bash: date +%s. In PHP: time(). The converter shows the current timestamp in real time.
What is the difference between Unix timestamp in seconds and milliseconds?
Standard Unix timestamp is in seconds (10 digits, e.g., 1700000000). JavaScript's Date.now() returns milliseconds (13 digits, e.g., 1700000000000). Divide milliseconds by 1,000 to get seconds. The converter accepts both formats.
