Frequently Asked Questions
What is the difference between a timestamp and a date?
A Unix timestamp is the number of seconds since 1970-01-01 00:00:00 UTC (milliseconds are the same with 3 decimals). The tool detects both automatically.
What is the difference between 10-digit and 13-digit timestamps?
A 10-digit timestamp is second-level, and a 13-digit one is millisecond-level. The tool detects and converts both automatically β no manual switching needed.
Does the result depend on the timezone?
The timestamp itself is absolute. The tool shows Beijing time, UTC, and your local timezone side by side for easy comparison.
Is my data uploaded to a server?
No. All conversion happens locally in your browser β no network required.
