,,会跳过空值splitstring。N305 C语言从GPS获得时间UTC，并把UTC转为CTS本地时间 时间转为秒+8小时

#include <stdio.h>
#include <string.h>
#include <time.h>
int splitString2(char dst[][15], const char *str, const char *spl) //会修改原字符串
{
    int n = 0;
    char *result = NULL;
    result = strtok((char *)str, spl);
    while (result != NULL)
    {
        strcpy(dst[n++], result);
        result = strtok(NULL, spl);
    }
    return n;
}
time_t datetime2sec(int year, int mon, int day, int hour, int min, int sec)
{
    struct tm tt;
    memset(&tt, 0, sizeof(tt));
    tt.tm_year = year - 1900;
    tt.tm_mon = mon - 1;
    tt.tm_mday = day;
    tt.tm_hour = hour;
    tt.tm_min = min;
    tt.tm_sec = sec;
    return mktime(&tt);

	char GPSArray[15][15] = {
   
   {0}};
	int num = splitString2(GPSArray, values, ","); //num=11正常 ，其他值无效
	
	printf("num=%d\r\n",num);
	for(i=0;i<num;i++)

		printf("%d,%s\r\n",i,GPSArray[i]);	
	}
    
	sscanf(GPSArray[8],"%*4s%02d", &gpsTime.Year);  	//sscanf(GPSArray[8],"%02d%02d%02d", &gpsTime.Day,&gpsTime.Month,&gpsTime.Year);
	sscanf(GPSArray[8],"%*2s%02d", &gpsTime.Month);
	sscanf(GPSArray[8],"%2d", &gpsTime.Day);
	sscanf(GPSArray[1],"%02d%02d%02d", &gpsTime.Hour,&gpsTime.Minute,&gpsTime.Second);

    printf("解析 DateTime:%d-%d-%d %02d:%02d:%02d\n",gpsTime.Year,gpsTime.Month,gpsTime.Day,gpsTime.Hour,gpsTime.Minute,gpsTime.Second);
           
	//time( &rawtime );
    rawtime=datetime2sec(gpsTime.Year+2000,gpsTime.Month,gpsTime.Day,gpsTime.Hour,gpsTime.Minute,gpsTime.Second)+8*60*60; //加8小时
   info = localtime( &rawtime );
   //rtc_api_set_time(gpsTime);
   printf("当前的本地时间和日期：%s", asctime(info));
	printf("\r\nend\r\n");
}

以为有13个分隔符就会切成14块。实际只有11个。空值跳过。
