如何在python中创建基于时间的BufferingHandler？

import logging
from logging.handlers import BufferingHandler, TimedRotatingFileHandler

class TimeBasedBufferingHandler(BufferingHandler):
    def __init__(self, filename, mode, delay):
        super().__init__(delay)
        self.log_filename = filename
        self.log_file_mode = mode

    def flush(self):
        """
        在flush()方法中，我们可以将日志消息写入到日志文件中。
        """
        with open(self.log_filename, self.log_file_mode) as f:
            for record in self.buffer:
                f.write(self.format(record) + '\n')
        super().flush()

    def emit(self, record):
        """
        在emit()方法中，我们将消息添加到缓冲区中。
        """
        super().emit(record)

def create_timed_buffering_logger():
    logger = logging.getLogger('timed_buffering_logger')
    logger.setLevel(logging.DEBUG)
    
    handler = TimeBasedBufferingHandler('timed_buffering.log', mode='a', delay=10)
    handler.setLevel(logging.DEBUG)
    
    formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')
    handler.setFormatter(formatter)
    
    logger.addHandler(handler)
    
    return logger

logger = create_timed_buffering_logger()
logger.debug('This is a debug message.')
logger.info('This is an info message.')
logger.warning('This is a warning message.')
logger.error('This is an error message.')
logger.critical('This is a critical message.')
