          :return:
              * date_this_year: (datetime) 当前月份的随机时间
  
          举例如下::
  
              print('--- GetRandomTime.date_time_this_year demo ---')
              print(GetRandomTime.date_time_this_year())
              print('---')
  
          执行结果::
      
              --- GetRandomTime.date_time_this_year demo demo ---
