Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the Unix Epoch). It is timezone-independent, always increases, and is the universal standard for storing time in databases and APIs.
Seconds vs milliseconds — how do I know?
A 10-digit timestamp (e.g. 1719847234) is in seconds. A 13-digit timestamp (e.g. 1719847234000) is in milliseconds. Our tool auto-detects based on the digit count.
How do I get the current Unix timestamp in code?
JavaScript: Math.floor(Date.now() / 1000) for seconds, Date.now() for ms. Python: int(time.time()). Go: time.Now().Unix(). Java: System.currentTimeMillis() / 1000. SQL: UNIX_TIMESTAMP() in MySQL, EXTRACT(EPOCH FROM NOW()) in PostgreSQL.
What is Unix Epoch (timestamp 0)?
Unix timestamp 0 = January 1, 1970 00:00:00 UTC. In IST (UTC+5:30) this is January 1, 1970 05:30:00. Use the "Unix Epoch" preset to see all formats.
Does this work offline?
Yes. The live counter and all conversions happen in your browser using JavaScript Date API. No server requests are made for any conversion.
