是这样的，我想实现这样的功能：

\n\n

在socket.io的服务端，监控当前系统的时间，并拿当前时间跟前一秒相比，如果两个时间的分钟数发生了变化，就发一条消息到client端。

\n\n

不知道该如何实现（代码，或者有例子给个链接也可以）？

\n\n

这结果可能类似于 socke.io官网上的volatile功能（每隔一分钟发一条消息），但实际过程是不一样的，volatile只是单纯的每隔多久就发一条消息，我上述的描述是需要实时的比较。

\n\n

我这么做的更进一步的想法是，去实时的监控一个文件（或者某个sqlite数据库），如果文件里的内容发生了变化，就发消息给客户端。

\n\n

node.js初学者求教，3ks。
