SntpTuning (NetPhantom® 8.0 Java API Specification)

java.lang.Object
- co.mindus.time.ntp.SntpTuning

```
public final class SntpTuning
extends Object
```
An immutable bundle of the tunable values a SntpClient uses: the destination UDP port and the accuracy/confidence heuristic constants.
These were originally compile-time constants inside SntpClient. They are bundled here so the server side (which reads and clamps them from server.ini) can hand a fully-formed, validated set to the poller without SntpClient needing to know anything about INI files or clamping. The class is pure JDK and dependency-free, like the rest of this package.

```
    Creates a tuning bundle.
    Parameters:
    port - The destination UDP port.
    penaltyPerStratum - Accuracy lost per stratum.
    maxDispersionPenalty - Maximum accuracy lost to root dispersion.
    maxRttPenalty - Maximum accuracy lost to round-trip delay.
    confidenceHighAt - HIGH-confidence accuracy threshold.
    confidenceMediumAt - MEDIUM-confidence accuracy threshold.
