look over these. i had to synthesis some .h files (e.g. Arduino.h) because i built this on my laptop

get.cpp

#include "Arduino.h"

#include "get.h"

//define ntp client to get time
WiFiUDP ntpUDP;
//NTPClient timeClient(ntpUDP, "pool.ntp.org"); //if you don't need Offset
NTPClient timeClient(ntpUDP, "pool.ntp.org", utcOffsetInSeconds);

const long utcOffsetInSeconds = 7200; //EU-Rome

//------ TIMESTAMP ------
unsigned long getTime(){
  timeClient.update();
  unsigned long Now = timeClient.getEpochTime();
  Serial.println(Now);
}//end getTime

get.h -- since get.h references NTPClient, i added NTPClient.h to it to avoid relying that it is defined in some other file using get.h and since HTPClient.h referenced a WiFiUDP, i assumed NTPClient.h inlcuded WiFiUDP.h

#ifndef _GET_h_
#define _GET_h_

#include "NTPClient.h"

//Set the utcOffsetInSeconds of your local zone
extern const long utcOffsetInSeconds;
extern NTPClient timeClient;

//------ TIMESTAMP ------
unsigned long getTime();

#endif

main.cpp (i needed to add main() to link completely)

#include "Arduino.h"
#include "get.h"

Serial_s Serial;

// -----------------------------------------------------------------------------
void setup() {

  //SERIAL
  Serial.begin(115200);

  //TIMETSAMP
  timeClient.begin(); //--> the error refers to this


}//Setup

void loop() {

}//Loop

// -----------------------------------------------------------------------------
int
main ()
{
    setup ();
    loop ();
}

i hope you see what was done. i just made it link. i believe knowing what is required in a .h is a bit of an art, but easily tested when building. minimize what is in a .h.
