I flashed the ds3231 example provided by the library:

2018/10/31 (Wednesday) 0:0:36
 since midnight 1/1/1970 = 1540944036s = 17835d
 now + 7d + 30s: 2018/11/7 12:30:42

Returning the correct unixtime with 1540944036, so it is getting even more strange…

Update:
I tried to make my code exactly like in the example writing the result in "testvar"

Code:

 DateTime testvar = RTC.now();
 Serial.print("Timestamp: ");
 Serial.println(now());
 Serial.print("Timestamp RTC Unix: ");
 Serial.println(testvar.unixtime());
 Serial.println(RTC.now().year());
 Serial.println(RTC.now().month());
 Serial.println(RTC.now().day());
 Serial.println(RTC.now().hour());
 Serial.println(RTC.now().minute());
 Serial.println(RTC.now().second());

same stuff:
Timestamp: 1540944934

Timestamp RTC Unix: 1573949734
