A wall-clock time is ambiguous without a zone: "14:00" means different instants in Delhi and Dublin. The converter asks explicitly — local or UTC — and applies the browser's IANA timezone database offset, including historical daylight-saving rules, so the epoch number you copy is the exact instant you meant.
Frequently Asked Questions

Default is your browser timezone; tick "as UTC" to match server-side values.
Why is my timestamp 5.5 hours off?
India is UTC+5:30 — switch the UTC checkbox to align with servers.
