Every tool uses the same engine as the rest of the site: times come straight
from the IANA Time Zone Database via your browser's Intl API, so
results are DST-correct for every zone, every day of the year. Everything runs
in your browser, no sign-up, no server round-trips, and the shareable tools
pack their whole state into a link.
