Hi Dmitry,

Thank you for your note. Yes, you are right.

The function in time-STM32F2xx.c/time-dummy.c is for dummy and redundant.
You can use gmtime. Additionally, you need to define XTIME and XGMTIME
in asn.c for operational system.

For further detail, you can refer "2.9 Time, wolfSSL Porting Guide"

Best Regards,

Kojo
