代码如下：

void timeCommand(redisClient *c) 

{ struct timeval tv; /* gettimeofday() can only fail if &tv is a bad address so we * don't check for errors. */ gettimeofday(&tv,NULL); addReplyMultiBulkLen(c,2); addReplyBulkLongLong(c,tv.tv_sec); addReplyBulkLongLong(c,tv.tv_usec); } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

逐一分析。

//自定义检查点: 1 2 3

struct timeval tv; //定义变量 //自定义检查点: 1 2 3 /* gettimeofday() can only fail if &tv is a bad address so we * don't check for errors. */ gettimeofday(&tv,NULL); //获取当前时间 //自定义检查点: 1 2 3 addReplyMultiBulkLen(c,2); //返回*2\r\n addReplyBulkLongLong(c,tv.tv_sec); //返回秒 addReplyBulkLongLong(c,tv.tv_usec); //返回微秒 //自定义检查点: 1 2 3

具体的格式这里就不分析了，有兴趣自己用wireshark抓包就知道了！
