用localtime

谢谢大神，可是时间输出不对，时间为１６:３３时，编译生成ＰＭ２６:１５８:００，是不是算法不对

#include<stdio.h>
#include<time.h>
int main()
{
    time_t ntime;
    struct tm *now;
    time(&ntime);
    now=localtime(&ntime);
    printf("%4d-%02d-%02d %02d:%02d:%02d\n",1900+now->tm_year,now->tm_mon+1,now->tm_mday,now->tm_hour,now->tm_min,now->tm_sec);
}
