Currently it's O(n) - we do `n` shifts of bytes within `StringBuilder`. This
can be reduced to O(1) improving the code like:
DateTimeFormatter dtf = new DateTimeFormatterBuilder()
.appendLiteral("Date:")
.padNext(20, ' ')
.append(DateTimeFormatter.ISO_DATE)
.toFormatter();
String text = dtf.format(LocalDateTime.now());
