I am working with a large sheet, where I would like some cells to clear after a certain time. They contain data that becomes out of date. For instance, I would like to clear contents of F16 after 5pm. The problem is there are alot of cells, most of which have a different time they would clear. It is also a shared sheet, so having to manually run a macro all the time would be too difficult. Is there any way to do this with a formula.?

Thanks
Paul
