time.h与linux/time.h,该如何解决

time.h与linux/time.h
Linux localhost.localdomain 2.6.18-53.el5

/usr/include/linux/time.h:9: 错误：‘struct timespec’ 重定义
/usr/include/time.h:122: 错误：‘struct timespec’ 的上一个定义
/usr/include/linux/time.h:15: 错误：‘struct timeval’ 重定义
/usr/include/bits/time.h:70: 错误：‘struct timeval’ 的上一个定义
/usr/include/linux/time.h:42: 错误：‘struct itimerspec’ 重定义
/usr/include/time.h:163: 错误：‘struct itimerspec’ 的上一个定义

我的int clock_gettime(clockid_t clk_id, struct timespec *tp);定义在include/linux/time.h

C/C++ code

#include <iostream>#include <linux/time.h>using namespace std;

C/C++ code

#include <iostream>#include <time.h>using namespace std;
