c – 将字符串从__DATE__转换为time_t

    char s_month[5];
    int month,day,year;
    struct tm t = {0};
    static const char month_names[] = "JanFebMarAprMayJunJulAugSepOctNovDec";

    sscanf(time,"%s %d %d",s_month,&day,&year);

    month = (strstr(month_names,s_month)-month_names)/3;

    t.tm_mon = month;
    t.tm_mday = day;
    t.tm_year = year - 1900;
    t.tm_isdst = -1;

    return mktime(&t);
