About this timestamp converter
Enter a Unix timestamp and convert it to local time, UTC, and ISO 8601 all at once — or go the other way and turn a date into epoch seconds and milliseconds. Auto-detect figures out whether your number is in seconds or milliseconds, and the Now button drops in the current time. Everything runs locally in your browser — nothing is uploaded. For the Y2038 problem, the seconds-vs-milliseconds ambiguity, and timezone gotchas, read the Unix timestamp guide.
