✅ Time of method differs between Stopwatch.GetTimestamp and DateTime.Now
Hi there, I have to codes, that differs only in the way that they are recording time of the same operation. It there a big deal that they are once use DataTime and TimeSpan and other Stopwatch.GetTimeStamp?
static void LMaxT()
{
DateTime startTime, stopTime;
TimeSpan totalTime = TimeSpan.Zero;
for (int i = 0; i < NumOfIter ; i++)
{
startTime = DateTime.Now;
bool Present = IsPresent_Linear(sourceTable, sourceTable.Length - 1);
stopTime = DateTime.Now;
totalTime += stopTime - startTime;
}
TimeSpan lenghtOfCalc = totalTime / NumOfIter;
Console.Write($"\t{lenghtOfCalc.TotalSeconds.ToString("F4")}s");
}
static void LinearMaxTim()
{
double ElapsedSeconds;
long ElapsedTime = 0, MinTime = long.MaxValue, MaxTime = long.MinValue, IterationElapsedTime;
for (int n = 0; n < (NumOfIter); ++n)
{
long StartingTime = Stopwatch.GetTimestamp();
bool Present = IsPresent_Linear(sourceTable, sourceTable.Length - 1);
long EndingTime = Stopwatch.GetTimestamp();
IterationElapsedTime = EndingTime - StartingTime;
ElapsedTime += IterationElapsedTime;
if (IterationElapsedTime < MinTime) MinTime = IterationElapsedTime;
if (IterationElapsedTime > MaxTime) MaxTime = IterationElapsedTime;
}
ElapsedTime -= (MinTime + MaxTime);
ElapsedSeconds = ElapsedTime * (1.0 / (NumOfIter * Stopwatch.Frequency));
Console.Write("\t" + ElapsedSeconds.ToString("F4")+"s");
}static void LMaxT()
{
DateTime startTime, stopTime;
TimeSpan totalTime = TimeSpan.Zero;
for (int i = 0; i < NumOfIter ; i++)
{
startTime = DateTime.Now;
bool Present = IsPresent_Linear(sourceTable, sourceTable.Length - 1);
stopTime = DateTime.Now;
totalTime += stopTime - startTime;
}
TimeSpan lenghtOfCalc = totalTime / NumOfIter;
Console.Write($"\t{lenghtOfCalc.TotalSeconds.ToString("F4")}s");
}
static void LinearMaxTim()
{
double ElapsedSeconds;
long ElapsedTime = 0, MinTime = long.MaxValue, MaxTime = long.MinValue, IterationElapsedTime;
for (int n = 0; n < (NumOfIter); ++n)
{
long StartingTime = Stopwatch.GetTimestamp();
bool Present = IsPresent_Linear(sourceTable, sourceTable.Length - 1);
long EndingTime = Stopwatch.GetTimestamp();
IterationElapsedTime = EndingTime - StartingTime;
ElapsedTime += IterationElapsedTime;
if (IterationElapsedTime < MinTime) MinTime = IterationElapsedTime;
if (IterationElapsedTime > MaxTime) MaxTime = IterationElapsedTime;
}
ElapsedTime -= (MinTime + MaxTime);
ElapsedSeconds = ElapsedTime * (1.0 / (NumOfIter * Stopwatch.Frequency));
Console.Write("\t" + ElapsedSeconds.ToString("F4")+"s");
}
