MKR ZERO - SD card and RTC problem

Hi everyone,

I have a small problem on my Arduino MKR ZERO. Basically, I use it to record some data on my SD card. Once the code is uploaded, the RTC is initialized. This data is really important because it is converted to a timestamp that becomes really useful to organise my data after. Everything works perfectly, until I want to put my SD Card back. At that moment, the Arduino initialises itself once again, and with it, the RTC. I cannot really believe that it’s a normal way for this type of Arduino to work, so I would like to hope that there is a way to solve that problem. Did this happen to any of you? I would be really glad to hear any suggestion about that problem. Cheers!
