Subject php timestamp firebird
Author yadajopp

In a php script of mine, I have the following mysql query.

UPDATE users SET logged_in=0, timestamp=timestamp where logged_in=1
and username='$Loginname' AND (now()+0)-(date_add(timestamp,interval
600 second))>=0");

now my question is, is there a simular function to date_add in
firebird? or is there another way to get the same result?
