Questions

What is the difference between seconds and milliseconds epoch?
Unix timestamps traditionally use seconds since Jan 1, 1970. JavaScript Date.now() and Java System.currentTimeMillis() use milliseconds, which are 1000x larger. A seconds timestamp is typically 10 digits, milliseconds is 13 digits.
Does the tool auto-detect the format?
Yes, if the input is less than 10^12, it is likely seconds; otherwise it is treated as milliseconds. Both formats are shown in the output.
How do I get the current epoch milliseconds?
In JavaScript use Date.now(), in Java use System.currentTimeMillis(), and in Python use int(time.time() * 1000). This tool also shows the current epoch time for reference.
Is the epoch milliseconds converter safe for production timestamps?
All conversions run locally in your browser. No timestamps are sent to a server, so you can safely convert production log timestamps without exposing system data.
