Unix时间戳字符串转int (unixtime)

#include <ctime>
#include <iostream>

using namespace std;

// 转换形如 2014-08-01 12:38:22 的时间戳到unixtime 
inline time_t GetUnixTime(const char *pszTimeStamp)
{
    struct tm stTime;
    memset(&stTime, 0, sizeof(stTime));

           &stTime.tm_hour, &stTime.tm_min, &stTime.tm_sec);

    stTime.tm_year -= 1900;
    stTime.tm_mon --;
