Re: one hour is/is not 60 minutes, that's the question...
Hello, mysql select version(); ++ | version() | ++ | 4.1.9-standard-log | ++ 1 row in set (0.00 sec) mysql Although I'm not fully aware of MySQL time/date symantecs, I would like to make a comment... mysql select addtime(now(), '00:00:00'); ++ | addtime(now(), '00:00:00') | ++ | 2005-02-15 16:49:17| ++ 1 row in set (0.00 sec) mysql select addtime(now(), '00:60:00'); There's no such time. 00:60:00 is a duration, not a time. So I too wonder what the warning was... ++ | addtime(now(), '00:60:00') | ++ | NULL | ++ 1 row in set, 1 warning (0.00 sec) mysql select addtime(now(), '01:00:00'); This is a valid time. Namely, 01:00 AM. ++ | addtime(now(), '01:00:00') | ++ | 2005-02-15 17:50:27| ++ 1 row in set (0.00 sec) in my opinion the result of the second and third example above must be the same. Perhaps there's another function to add durations?

Is the DATE_ADD(time, INTERVAL) an option?

Nope. Leap seconds do not accumulate to leap minutes; thus there's no hour with 60 minutes. I'm not sure about the silent conversion to NULL; PostgreSQL throws an error stating 'interval field value out of range: 00:60:00'. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
