}

以上是获取当前年月日

---------------------------------详解的其他方法

linux,ios下的

struct cc_timeval now;   
CCTime::gettimeofdayCocos2d(&now,NULL);   
struct tm *tm;  
tm = localtime(&now.tv_sec);  
int year = tm->tm_year + 1900;  
int month = tm->tm_mon + 1;  
int day = tm->tm_mday;  
int hour=tm->tm_hour;  
int minute=tm->tm_min;  
int second=tm->tm_sec;  
long millSecond=now.tv_sec * 1000 + now.tv_usec / 1000;

struct tm *tm;  
time_t timep;  
time(&timep);  
tm = localtime(&timep);  
int year = tm->tm_year + 1900;  
int month = tm->tm_mon + 1;  
int day = tm->tm_mday;  
int hour=tm->tm_hour;  
int minute=tm->tm_min;  
int second=tm->tm_sec;
