Re: [PATCH v2020.01] tool: ifwitool: The function localtime() can return NULL.

This will cause the local_time pointer is passed as the 4th argument to function strftime() to also point to NULL. This result in a segmentation fault. Thus, it's necessary to add a check of the local_time pointer to NULL.
