Pick a date, a time and a source zone, and read that moment in as many zones as you like: add, remove and reorder target rows, each showing the local wall time, the UTC offset in effect, a DST marker when summer time applies, the localized zone name, and a copyable ISO 8601 stamp with offset. Local times that occur twice at a fall-back transition, or not at all in a spring-forward gap, are called out plainly. The same-moment slider shifts the hour across all rows at once. Zone rules, DST transitions and names come from your browser’s built-in Intl API — no timezone database is bundled and nothing touches the network. Complements the timestamp converter (epoch-centric) and the date calculator (arithmetic): this tool is wall-clock across zones.
