linux 下 C 程序获取时间的例子

获取时间：

#include
#include

int main()
{
    time_t t;
    struct tm *lt;

    t = time(NULL);//获取秒数计的时间//time(&t)
    lt = localtime(&t);//获取本地时间

    printf("local time:%d/%d/%d  %d:%d:%d   week:%d\n", lt->tm_year+1990, lt->tm_mon, lt->tm_mday, lt->tm_hour\
                    , lt->tm_min, lt->tm_sec, lt->tm_wday);

    lt = gmtime(&t);//utc 时间
    printf("UTC:%d/%d/%d  %d:%d:%d   week:%d\n", lt->tm_year+1990, lt->tm_mon, lt->tm_mday, lt->tm_hour\
                    , lt->tm_min, lt->tm_sec, lt->tm_wday);

    printf("%s\n", asctime(lt));
    printf("%s\n", ctime(&t));

    return 0;
}
