class LocalTime {
public String toString() {
// ...
if (nanoValue % 1000_000 == 0) {
buf.append(Integer.toString((nanoValue / 1000_000) +
1000).substring(1));
} else if (nanoValue % 1000 == 0) {
buf.append(Integer.toString((nanoValue / 1000) +
1000_000).substring(1));
} else {
buf.append(Integer.toString((nanoValue) +
1000_000_000).substring(1));

}
}
Currently, LocalTime.toString handles nanos by adding a value and then
subString(1) to fill it with zeros. Using StringBuilder.repeat is more concise
and has better performance.
