Display calculation time
Jan 21st, 2010, 1:11pm  
I would like to print to the console how long a calculation time was, atm i use:

   long startTimeMin = minute();
   long startTimeSec = second();

with this at the end:

   println(" time: " + (minute()-startTimeMin) +" min "+ (second()-startTimeSec) +" sec");

The problem is that if it's 18:57 for example then it ends up in -7 min cause a new hour started.

The problem with millis() is that it's much harder to read, specialy since my upcoming calculation time will be between 8 and 12 hours.

Is there some trick to fix this?

Code:
int start;
void setup()
{
  // Probably near zero...
  int start = millis();
}

void draw()
{
  background(frameCount);
}

void mousePressed()
{
  int end = millis();
  int timeSpent = (end - start) / 1000; // Seconds spent
  int h = timeSpent / 3600;
  timeSpent -= h * 3600;
  int m = timeSpent / 60;
  timeSpent -= m * 60;
  println("Spent: " +
	h + " hours, " +
	m + " minutes, " +
	timeSpent + " seconds");
}

Tested with only a few minutes.

Thx a lot, i'm going to test tonight if the hours run proper.

for who's intrested:

But this line before a big for loop or something:
Code:

    int startTime = millis();


And this one after
Code:

    printSpentTime(startTime);


Code:

void printSpentTime(int startTime){
  int end = millis();
  int timeSpent = (end - startTime) / 1000; // Seconds spent
  int h = timeSpent / 3600;
  timeSpent -= h * 3600;
  int m = timeSpent / 60;
  timeSpent -= m * 60;
  println("Spent: " +h + " hours, " +m + " minutes, " +timeSpent + " seconds");
}
