public class Example
{
    public static long ElapsedNanoseconds(long startTimestamp)
    {
        long now = ProfilerUnsafeUtility.Timestamp;
        var conversionRatio = ProfilerUnsafeUtility.TimestampToNanosecondsConversionRatio;
        return (now - startTimestamp) * conversionRatio.Numerator / conversionRatio.Denominator;
    }
}
```
