Does the timestamp converter use my timezone?

Local date input and local output use your browser timezone. ISO output is UTC.

Can it handle milliseconds?

Yes. Very large timestamp values are treated as milliseconds, and both seconds and milliseconds are shown.

No. Time conversion is calculated entirely in your browser.
