Document

Returns the arithmetic mean of x and y , rounded toward negative infinity.

Usage

From source file:com.teradata.benchto.driver.listeners.BenchmarkServiceExecutionListener.java

private void checkClocksSync() {
    long timeBefore = System.currentTimeMillis();
    long serviceTime = benchmarkServiceClient.getServiceCurrentTime().toEpochMilli();
    long timeAfter = System.currentTimeMillis();

    long driftApproximation = Math.abs(LongMath.mean(timeBefore, timeAfter) - serviceTime);
    long approximationPrecision = timeAfter - LongMath.mean(timeBefore, timeAfter);

    Duration driftLowerBound = Duration.of(driftApproximation - approximationPrecision, ChronoUnit.MILLIS);

    if (driftLowerBound.compareTo(MAX_CLOCK_DRIFT) > 1) {
        throw new RuntimeException(
                format("Detected driver and service clocks drift of at least %s, assumed sane maximum is %s",
                        driftLowerBound, MAX_CLOCK_DRIFT));
