LongPress/ShortPress button two functions

Here is the current working code that prints only once after every time the loop is satisfied. Again, I want to extend this program to using another pair of switch/led with the same functionality in the same program. Thanks for your patience with me.

int ledPin = 13;
int buttonPin = 2;
int firsttimeflag = 1;
unsigned long startTime;
unsigned long pressTime;
unsigned long timeInterval = 10000;
int printflag = 1;

void setup()
{
pinMode(ledPin, OUTPUT);
pinMode(buttonPin, INPUT);
digitalWrite(buttonPin, HIGH);

Serial.begin(9600);
}

void loop()
{
if(digitalRead(buttonPin) == LOW){
 if(firsttimeflag == 1){
  startTime = millis();
  firsttimeflag=0;
 }
 pressTime = millis()- startTime;
 if(pressTime >= 1){
  Serial.print("Time: ");
  Serial.print(pressTime);
  Serial.print(" milliseconds ");
  Serial.print(int(pressTime/1000));
  Serial.println(" seconds");
 }
 if(pressTime>timeInterval){
  digitalWrite(ledPin, HIGH);
  if(printflag == 1)
  Serial.println("holding");
  printflag = 0;
 }
}
else if(firsttimeflag == 0)
{
 firsttimeflag = 1;
 printflag = 1;
 Serial.println("Time: 0 milleseconds; 0 seconds");
 digitalWrite(ledPin, LOW);
}
}
