Frequently Asked Questions
How does it know if my timestamp is in seconds or milliseconds?
It checks the number of digits — Unix timestamps in seconds are 10 digits for dates around now, while millisecond timestamps are 13. Anything with more than 11 digits is treated as milliseconds automatically.
What timezone is the "Local" result shown in?
Your browser's own system timezone. The UTC and ISO 8601 results are timezone-independent, so use those if you need a value to share with someone in a different timezone.
Can I convert a date back into a timestamp?
Yes — use the "Date → Timestamp" panel on the right; pick or type a date and time and both the seconds and milliseconds versions appear instantly.
Does the current timestamp update automatically?
Yes — it ticks forward every second for as long as the page stays open, so you can always grab the exact current Unix time.
