Converts Unix time (seconds, milliseconds, microseconds or nanoseconds — detected from magnitude unless a unit is chosen), ISO 8601, RFC 2822 and "now" into every representation: Unix units, ISO/RFC strings, the selected IANA timezone with offset, weekday, day of year, ISO week and relative time. Up to 1,000 lines per run; invalid lines are reported individually. Everything runs locally.
auto: < 10^11 seconds · < 10^14 ms · < 10^17 µs · else ns.
Local rendering and offset use this zone; input without an offset is treated as UTC.
Reference point for the relative column; empty = now.
