What is a timestamp?
A Unix timestamp counts seconds (10 digits) or milliseconds (13 digits) since 1970-01-01 00:00:00 UTC — how computer systems commonly record time, frequent in databases and logs.
How do I convert a timestamp to a date?
Paste and click Timestamp→Date; the tool auto-detects seconds/ms and shows both UTC and local time (Beijing time), no manual math.
How do I tell seconds from milliseconds?
10 digits = seconds; 13 = milliseconds. Auto-detected on paste — no manual switching, avoiding off-by-1000 errors.
Is online timestamp conversion safe?
Safe. Conversion runs locally with zero upload, suitable for logs and API time fields with business data.
What is timestamp conversion best for?
Debugging API responses, parsing DB time columns, converting log times, verifying order creation times and measuring API latency.
Why is my time 8 hours off?
Timezone difference. The tool shows UTC and local (UTC+8) side by side; pick local timezone for the correct value.
Are there limits on free use?
No. Free, no registration, supporting second/millisecond/microsecond precision.
Are negative timestamps supported?
Yes — negative values represent pre-1970 times and convert correctly.
