linux 下时间字符串和time_t类型之间的相互转化

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


time_t  ConvertStrtoTime(char * szTime)
{
    tm tm_;  
    time_t t_;  
    strptime(szTime, "%Y-%m-%d %H:%M:%S", &tm_); //将字符串转换为tm时间  
    tm_.tm_isdst = -1;  
    t_  = mktime(&tm_);                         //将tm时间转换为秒时间  
    //t_ += 3600;                                //秒数加3600 
    return t_;

}

int main()
{
 char szTime[128] = {0};
        char szBuf[64] = {0};
        time_t t; 
        tm  sttm;
        strcpy(szTime, "2015-09-01 17:57:47");
        t = ConvertStrtoTime(szTime);
        printf("t:%ld \n", t);

        sttm = *localtime(&t);//输出时间  
        strftime(szBuf, 64, "%Y-%m-%d %H:%M:%S", &sttm);  

        printf("szBuf:%s \n", szBuf);
 return 0;
}

运行效果：

[root@localhost time]# ./convert 
t:1441101467 
szBuf:2015-09-01 17:57:47 
[root@localhost time]#
