根据日期计算星期

     字符串中存着年月日的信息，将这些数据解析出来，并利用公式计算对应星期：

                     p = time_str_temp;

                     i=0;
                    while((p != NULL) && (*p != '\0')  && (*p != '/'))
                    {
                            year[i++] = *p++;
                    }
                    p++; // '/'
                    i = 0;
                    memset(month, 0, sizeof(month));
                    while((p != NULL) && (*p != '\0') && (*p != '/'))
                    {
                            month[i++] = *p++;
                    }

                    p++; //'/'
                    i = 0;
                    memset(day, 0, sizeof(day));
                    while((p != NULL) && (*p != '\0'))
                    {
                            day[i++] = *p++;
                    }

                    timeyear = atoi(year);
                    timemonth = atoi(month);
                    timeday = atoi(day);

                if((timemonth == 1) || (timemonth ==2))
                {
                    timemonth = timemonth+12;
                    timeyear = timeyear-1;       
                }
                if((timemonth<13 && timemonth>0) && (timeday<32 &&timeday>0))
                {
                    time_week = (timeday+2*timemonth+3*(timemonth+1)/5+timeyear+timeyear/4-timeyear/100+timeyear/400)%7+1;
                }
