Well, I am hopefully not an idiot (but who knows?), so of course I knew that. I didn't ask for an evaluation (if that's the correct word in this situation, I don't know, I don't usually speak English) of my project (that's why I didn't mention what I was trying to do and that's the reason that I'm not going to, but let's say that I want to measure times that usually land somewhere at 0,5 s. How can I do that with now() if its precision is 1 s? Impossible, okay? So I would need something better. At least I know now that this isn't possible with OpenOffice.org BASIC, and that's exactly what I wanted to know. Thanks. >> >> And how can 16 ms be the best precision due to IBM PC hardware design? > > The original IBM PC was Stone Age computing, compared to current PC.

Yes, I kind of figured that (well, not the XP part but Windows). I just mentioned that I don't use it to avoid Windows specific information that's not relevant to me anyway, nothing to be upset about. Sorry.
