这几天不忙，终于可以学习了写了个闹钟跟大家分享下

struct cc_timeval now;

CCTime::gettimeofdayCocos2d(&now, NULL);

struct tm * tm;

tm = localtime(&now.tv_sec);

nHour = tm->tm_hour;

nMinute = tm->tm_min;

nSecond = tm->tm_sec;

CCLog("时%d 分%d 秒%d",nHour,nMinute,nSecond);

CCLog("日%d 月%d 年%d",tm->tm_mday,tm->tm_mon+1,tm->tm_year +1900);

CCLog("星期%d 本年的第%d天是否开夏令时%d",tm->tm_wday,tm->tm_yday+1,tm->tm_isdst);

CCLog("%ld 当前时区的名字%s",tm->tm_gmtoff,tm->tm_zone);

this->schedule(schedule_selector(HelloWorld::timeUpdate), 1);

void HelloWorld::timeUpdate(){

CCSprite * miaozhen = (CCSprite *)getChildByTag(miaozhen_tag);

CCSprite * shizhen = (CCSprite *)getChildByTag(shizhen_tag);

CCSprite * fenzhen = (CCSprite *)getChildByTag(fenzhen_tag);

nSecond++;

if (nSecond==60) {

nSecond = 0;

nMinute++;

if (nMinute == 60) {

nMinute = 0;

nHour++;

if (nHour== 24) {

nHour = 0;

}

int ss = nHour;

if (ss>=12) {

ss = nHour - 12;

}

shizhen->setRotation(CC_RADIANS_TO_DEGREES(ss*1.0/12*2*3.14)-90);

fenzhen->setRotation(CC_RADIANS_TO_DEGREES((nMinute+1)*1.0/60*2*3.14)- 15);

miaozhen->setRotation(CC_RADIANS_TO_DEGREES((nSecond+1)*1.0/60*2*3.14)- 15);

CCLog("%d -- %d -- %d",nHour,nMinute,nSecond);

}
