Review Comment:
`S` does not have a nanosecond precision. The Javadoc of
[`DateTimeFormatter`](https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html)
says:
> **Fraction**: Outputs the nano-of-second field as a fraction-of-second.
The nano-of-second value has nine digits, thus the count of pattern letters is
from 1 to 9. If it is less than 9, then the nano-of-second value is truncated,
with only the most significant digits being output.
So `S` should print the most significant digit of nanoseconds (i.e.
deciseconds)
