RTC Management

Hi,

I'm currently evaluating FlashDB implementation for remplacement to LittleFS that has shown bad performance for large datalog.

I would like to know what append if users set a date anterior to the max one in tsbd. (or in case of RTC battery failure).

PS : i need the timestamp of each entry to be real due to the fact that a computer will set command to get entry by timestamp.

Thanks
