node.js – 可以在Winston中进行每小时的日志轮换吗？

请查看以下示例代码：

var winston     = require ('winston');
var path        = require ('path');

var transports  = [];

transports.push(new winston.transports.DailyRotateFile({
  name: 'file',datePattern: '.yyyy-MM-ddTHH',filename: path.join("some_path","log_file_name.log")
}));

var logger = new winston.Logger({transports: transports});

// ... and logging
logger.info("some info log ...",{exTradata: 'abc'});

文件名如下：log_file_name.log.2013-12-17T16,log_file_name.log.2013-12-17T17等.

我希望这会有所帮助.
