cocos2d-x3.3获取时间

一、获取时间

struct tm *tm;

time_t timep;

#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)

time(&timep);

#else

struct timeval tv;

gettimeofday(&tv, NULL);

timep = tv.tv_sec;

#endif

tm = localtime(&timep);

int year = tm->tm_year + 1900;//年

int month = tm->tm_mon + 1;//月

int day = tm->tm_mday;//日

二、获取两个日期相差多少天

1、获取当前日期的天数

GetAbsDays(MyDate x) {

int i;

int month_day[] = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };

int year = x.year - 1;

int days = year * 365 + year / 4 - year / 100 + year / 400;

if (x.year % 4 == 0 && x.year % 100 != 0 || x.year % 400 == 0)

month_day[1]++;

for (i = 0; i < x.month - 1; i++)

days += month_day[i];

days += x.day - 1;

return days;

}

2、GetAbsDays(MyDate1 )- SignDialog::GetAbsDays(MyDate2);

三、通过时间戳计算时间差

1、获取当前时间（秒）

time_t t = time(0);

2、保存时间

Data data;

data.copy((unsigned char *) &t, sizeof(t));

UserDefault::getInstance()->setDataForKey("time_1", data);

3、取时间

auto d = UserDefault::getInstance()->getDataForKey("time_1",Data());

time_t lastExitTime = *((time_t*)d.getBytes());

time_t currentTime= time(0);

time_t time=currentTime-lastExitTime;

4、换算为分钟

int k=time/60;
