Timestamp Converter FAQ
Answers to common questions about behavior, privacy, and practical usage.
Does this tool accept seconds or milliseconds?
Yes. The converter detects short Unix second timestamps and longer millisecond timestamps, then shows both formats.
Why does local time differ from UTC?
UTC is a global reference time. Local time uses your browser time zone, which may include offset and daylight saving rules.
Can I convert the current time?
Yes. Use the current time button to load the current timestamp and generate matching second and millisecond values.
Is timestamp conversion local?
Yes. Date conversion uses browser APIs and does not send timestamp values to a server.
