Re: SQL timestamp duration can't be trusted?

Thanks, Pete, that works fine. Now for seconds, it looks like I can use the time function against a timestamp, take the difference in times, and apply the hour(), minute(), and second() functions. They come out negative.

Cool!

I want to get the duration in seconds between 2 timestamps in SQL. I have looked at the duration from subtracting 2 timestamps. But this does not seem a reliable way to do this, when leap years Feb 29 are involved. Or, actually, when relatively long periods are involved - 2 months can be anything from 59 -62 days.


Vern,

Try "select days(date2) - days(date1)". Should give you the actual number of days between two dates.
