    Serial.print(':');
    Serial.print(t.minute);
    Serial.print(':');
    Serial.print(t.second);
    Serial.print(' ');
    Serial.print(t.day);
    Serial.print(':');
    Serial.print(t.month);
    Serial.print(':');
    Serial.println(t.year);
    // or //
    Serial.print(t.timeString());
    Serial.print(' ');
    Serial.println(t.dateString());
