Thanks Slabbi, I do realize what it is, but I can't figure out for the life of me how to use it in my SQL statement. From what I can assume from the FAQ, is that I have to include something in the place of: (timestamp now). I've tried adding quotes ('') around it, taking out the parentheses ( & ), I've tried 'time()' with & without quotes.
Timestamp should just be a fixed figure (whatever the current time right now is), so all I need to know is what the syntax in php/Joomla/mySQL for uddeIM is, and if anyone could help me with that, I'd really appreciate it.
