説明

Gets conversion ratio from Profiler timestamp to nanoseconds.

Use to convert profiler timestamp value obtained with GetTimestamp to nanoseconds.

using Unity.Profiling.LowLevel.Unsafe;

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