why sould I use before (instead of after)?
isnt it a little dangerous in transactions? /hope not/

I know difference between both forms. The question is rather about if
timestamp updating shouldnt be run AFTER update which I think is closer
to a real world situations (of course evth vary). But maybe there are
some probles with after, which I dont know about?

Just being curious...
