Unix Timestamp Converter

Programmers pass time as a single growing integer, but people read a zone label and a calendar. Paste a seconds or millisecond value, and read the UTC and your browser’s local time at once. The Unix epoch and POSIX time are defined in UTC; leap seconds are skipped in the usual integer clock—treat the output as practical, not a legal-time archive.
