Is daylight saving taken into account?

Yes. The offset is calculated for the date you choose, so the answer is right either side of a clock change.

Is anything sent to a server?

No. The conversion uses the time zone database built into your browser.

JavaScript is turned off. InspireTools processes files in your browser, so the tools need JavaScript to run.
