Unix timestamp converter
Turn an epoch value into a readable date, or a date into a timestamp. The unit is detected from the number of digits, so seconds, milliseconds, microseconds and nanoseconds all just work. See ISO 8601, RFC 2822, relative time and the week number, in any time zone, and do date math too.
