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.

Convert India Standard Time (IST) to US Eastern Time (EST), with daylight saving handled.
