linux下c/c++ 常用时间和字符串互相转化介绍
c/c++ 中经常会遇到时间和字符串互相转化的情形
用以下2个函数来转就很方便了
1、时间转字符串函数
size_t strftime( char *strDest, size_t maxsize, const char *format, const struct tm *timeptr );
2、字符串转时间函数
char *strptime(const char *s, const char *format, struct tm *tm);
- #include
- #include
-
-
- int main()
- {
- struct tm tm_time;
- strptime("2010-11-15 10:39:30", "%Y-%m-%d %H:%M:%S", &tm_time);
- printf("%ld/n", mktime(&tm_time));
- printf("-------------------------------------/n");
-
-
- char szBuf[256] = {0};
- time_t timer = time(NULL);
- strftime(szBuf, sizeof(szBuf), "%Y-%m-%d %H:%M:%S", localtime(&timer));
- printf("%s/n", szBuf);
-
- return 0;
- }
