brew 中的时间格式转换

char  * pACNowStr = NULL;
    JulianType  jtNow;

    ISHELL_GetJulianDate(pIShell, , &jtNow);
    pACNowStr = (char *)MALLOC(* sizeof(char));

    SPRINTF(pACNowStr,"%04i%02i%02i%02i%02i%02i",//%02i表示将整数格式化为2位字符不够则在左边填补0
            jtNow.wYear,
            jtNow.wMonth,
            jtNow.wDay,
            jtNow.wHour,
            jtNow.wMinute,
            jtNow.wSecond);

    DBGPRINTF("current datetime is %s", pACNowStr );

    FREEIF(pACNowStr);
