ok so changing the line to the below has worked

sprintf(line, "%10ld %6s %7s", now.unixtime(), temp, press1);

I have now tried to see the filesize using

File Nautilus; // The file with your data in it.
uint32_t fileSize = Nautilus.size(); // The total file size.
Nautilus.seek(fileSize - 52);
  
//  Serial.print(Nautilus.size());
  //  Serial.println("---");

I have tried a few different combinations of the above however none of them have producing anything only "0"

SD card is ready to use.
