i apologize for this stupid question, ive seen many code for syncing PC time to arduino.. but what particular function is used to do this?.. is it the getPCtime() function?

I've seen this one:

void setup()
{
  Serial.begin(9600);
  Serial.println(F(__DATE__));
  Serial.println(F(__TIME__));
}

void loop()
{}
