Does this account for daylight saving time?

Yes — the conversion uses your browser’s built-in timezone database, which already accounts for DST rules and their change dates in each zone.

Why is only a short list of timezones offered?

These cover the timezones most "what time is it in X" searches are actually about; a full list of all ~400 IANA zones would be less usable, not more.

No — the conversion runs entirely in your browser.

See what time it is in another timezone for any date and time you pick.
