Get better results
Tips from how Timestamp Converter actually works, and mistakes worth avoiding.
Pro tips
- Keep a working copy of your input before running a destructive operation — undo is a browser back-button, not a history stack.
- When something looks wrong, check the start of the input first — most parsing errors cascade from one early character.
- Bookmark this page. It is a static URL with no login, so it works the same way every time you need it.
Common mistakes
- Assuming a paid tool would give a more "official" result — the underlying parsing logic is the same either way.
- Not checking for trailing commas, smart quotes, or copy-pasted invisible characters — the most common source of a confusing error.
- Working directly on the only copy of an important file instead of a duplicate.
Frequently asked questions
About Timestamp Converter and how Tarumak Studio works.
What is a UNIX timestamp?
A UNIX timestamp is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is the standard way computers represent moments in time.
Why does the tool auto-detect seconds vs milliseconds?
JavaScript uses milliseconds, most backend systems use seconds. If the input is 13 digits or more it is treated as milliseconds and divided by 1000 automatically.
Can I convert a specific date to a UNIX timestamp?
Yes — use the Human to Unix section to pick any date and time and get the corresponding UNIX timestamp in both seconds and milliseconds.
Is Timestamp Converter really free?
Yes — completely free, with no usage limits, no watermarks and no premium wall. Every tool on Tarumak Studio is free to use.
Do I need to create an account?
No. There is no sign-up, no login and no email required. Open the tool and use it immediately.
Is my input sent to a server?
No. Timestamp Converter processes everything you type or paste locally in your browser — nothing is ever sent to a server.
Does it work on mobile?
Yes. The tool runs in any modern browser on desktop, tablet or phone — no app install needed.
