一、代码如下：
#include <stdio.h> #include <time.h> int main() {     time_t timep;     struct tm *p;     time(&timep);     p = localtime(&timep); //此函数获得的tm结构体的时间，是已经进行过时区转化为本地时间     //p = gmtime(&timep); //把日期和时间转换为格林威治(GMT)时间的函数     printf("Year:  %d\n", 1900+p->tm_year);     printf("Month:  %d\n", 1+p->tm_mon);       printf("Day:  %d\n", p->tm_mday);       printf("Hour:  %d\n", p->tm_hour);       printf("Minute:  %d\n", p->tm_min);       printf("Second:  %d\n",  p->tm_sec);       printf("Weekday:  %d\n", p->tm_wday);       printf("Days:  %d\n", p->tm_yday);       printf("Isdst:  %d\n", p->tm_isdst);   }

二、执行如下：
[root@test http_pcap_codes]# ./a.out
Year:  2014
Month:  2
Day:  8
Hour:  16
Minute:  55
Second:  9
Weekday:  6
Days:  38
Isdst:  0

上面的这些日期可以通过c函数连接起来实现：20140208 的按时间的目录结构
原代码来自里面localtime写错了：

直接整数转也成：
snprintf(szValue,100,"%04d%02d%02d",1900+p->tm_year,1+p->tm_mon,p->tm_mday);                                                        
printf("%s",szValue)
#include <stdlib.h> #include <stdio.h> #include <time.h> #include <ctype.h> int main() {     time_t timep;     struct tm *p;     char szValue[1024];     time(&timep);                                                                                                                                                 p = localtime(&timep); //此函数获得的tm结构体的时间，是已经进行过时区转化为本地时间     snprintf(szValue,1024,"%04d%02d%02d",1900+p->tm_year,1+p->tm_mon,p->tm_mday);     printf("%s",szValue); }
整数转为char后再进行snprintf转代码%s（简单示例），snprintf参考：http://jackxiang.com/post/3736/
#include <stdlib.h> #include <stdio.h> #include <time.h> #include <ctype.h> int main() {     time_t timep;     struct tm *p;     char szValue[1024];     char Y[6];     char M[6];     char D[6];     time(&timep);     p = localtime(&timep); //此函数获得的tm结构体的时间，是已经进行过时区转化为本地时间     printf("Year:  %d\n", 1900+p->tm_year);     printf("Month:  %d\n", 1+p->tm_mon);       printf("Day:  %d\n", p->tm_mday);       printf("Hour:  %d\n", p->tm_hour);       printf("Minute:  %d\n", p->tm_min);       printf("Second:  %d\n",  p->tm_sec);       printf("Weekday:  %d\n", p->tm_wday);       printf("Days:  %d\n", p->tm_yday);       printf("Isdst:  %d\n", p->tm_isdst);       sprintf(Y, "%04d", 1900+p->tm_year);     sprintf(M, "%02d", 1+p->tm_mon);     sprintf(D, "%02d", p->tm_mday);     snprintf(szValue,1024,"%s%s%s",Y,M,D);     printf("%s",szValue); } ]]> http://www.jackxiang.com/post//#blogcomment <user@domain.com> Thu, 01 Jan 1970 00:00:00 +0000 http://www.jackxiang.com/post//#blogcomment
