In the JDK, it's implemented as:
public static void sleep(long millis, int nanos)
throws InterruptedException {
if (millis < 0) {
throw new IllegalArgumentException("timeout value is negative");
}
if (nanos < 0 || nanos > 999999) {
throw new IllegalArgumentException(
"nanosecond timeout value out of range");
}
if (nanos >= 500000 || (nanos != 0 && millis == 0)) {
millis++;
}
sleep(millis);
}
which means the nanos
argument doesn't do anything at all.
Is the idea behind it that on hardware with more accurate timing, the JVM for it can provide a better implementation for it?
