Generate CSR example compile error: incomplete type 'struct tm'

[torntrousers]

Hello. I'm trying your CSR generating example on an Arduino but the compile fails with:

:\Arduino\arduino-1.8.12\libraries\wolfSSL\asn.c: In function 'SetTime':

C:\Arduino\arduino-1.8.12\libraries\wolfSSL\asn.c:10402:29: error: dereferencing pointer to incomplete type 'struct tm'

     output[i++] = itob((date->tm_year % 10000) / 1000);

                             ^

C:\Arduino\arduino-1.8.12\libraries\wolfSSL\asn.c: In function 'SetValidity':

C:\Arduino\arduino-1.8.12\libraries\wolfSSL\asn.c:10461:15: error: storage size of 'localTime' isn't known

     struct tm localTime;

               ^

Is there some time setting somewhere I'm missing?

Thanks!

My user_settings.h file has this:
