(原创)GMT时间转本地时间

代码直接上了，其中timezone是C runtime libary的全局变量

CString GMTToLocalTime(const char *pGMTTimeToLocalTime)
{    
    struct tm newtime;
    CString szTime = "";
    if (strlen(pGMTTimeToLocalTime) > 0)
    {
        int nYear,nMonth,nDay,nHour,nMinute,nSecode,nMs;
        sscanf(pGMTTimeToLocalTime,"%04d-%02d-%02dT%02d:%02d:%02d.%dZ",
            &nYear,&nMonth,&nDay,&nHour,&nMinute,&nSecode,&nMs);
        newtime.tm_year = nYear - 1900;
        newtime.tm_mon = nMonth - 1;
        newtime.tm_mday = nDay;
        newtime.tm_hour = nHour;
        newtime.tm_min = nMinute;
        newtime.tm_sec = nSecode;
        newtime.tm_wday = 0;
        newtime.tm_yday =0;
        newtime.tm_isdst = 0;
        long time = mktime(&newtime) - timezone;
        struct tm *pnewtime;
        pnewtime = localtime(&time);
        if (NULL != pnewtime)
        {
            szTime.Format("%04d-%02d-%02dT%02d:%02d:%02d.%dZ",
                pnewtime->tm_year + 1900 ,pnewtime->tm_mon + 1,
                pnewtime->tm_mday,pnewtime->tm_hour,pnewtime->tm_min,pnewtime->tm_sec,nMs);
        }
    }
    return szTime;
}
