Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is the standard way computers track time across systems.
Does this converter handle milliseconds?
Yes. The converter automatically detects whether your input is seconds or milliseconds. Entries longer than 10 digits are treated as milliseconds.
Can I convert a human date back to a timestamp?
Yes. Use the date picker to select any UTC date and time — the tool instantly shows the corresponding Unix timestamp in both seconds and milliseconds.
Is my data sent anywhere when I convert?
No. All conversion happens client-side inside your browser. No data is ever collected, uploaded, or stored.
