Hi Thanks for your reply, I have tried this using NOW() and NOW()+0, there is no difference, I think I have narrowed the problem down to the time part of the timestamp being disregarded, as I have written the query below it is making the calculation using days rather than seconds......
This should really be a rather simple query to achieve, but it is turning into a big headache.....
