c语言中读取当前时间的源代码

#include <stdio.h>
#include <time.h>

void main()
{
struct tm *newtime;
time_t long_time;
time( &long_time );
newtime = localtime( &long_time );
printf("%d-%d-%d-%d:%d:%d\n", newtime->tm_year + 1900,
newtime->tm_mon + 1,
newtime->tm_mday,
newtime->tm_hour,
newtime->tm_min, newtime->tm_sec);
}

用shell调用dos的date命令! 咔咔~~~
