我寫幾個mysql的命令,像這樣:爲什麼mysql函數now()有時會返回00:00:00?
insert into news_seeds values(1, 'http://www...', 0, 0, 60, now(), 10, now());
insert into news_seeds values(2, 'http://www...', 0, 0, 60, now()-10, 10, now()-2);
insert into news_seeds values(3, 'http://www...', 0, 0, 60, now()-20, 10, now()-4);
...
但我覺得有時候現在只返回00:00:00,爲什麼呢?
