I think my confusion came from assuming they were answering the question that was asked. :-) The RM says "An upper bound on the drift rate of Clock with respect to REAL TIME." (emphasis mine) Aonix gave me an answer with respect to the system clock. Those are clearly not the same thing. So someone looking here for Clock's drift rate with respect to real time will not get it. In all fairness to Aonix, there's no way they could know what the clock drift rate for the hardware in any particular PC is. But they should have said that, rather than answering half the question in an incredibly terse manner. I guess I was mostly posting this to see if this is a just a farcical non- compliance with the documentation standard, or if I'm misunderstanding the standard. There are several other examples I could site, but this one was the funniest. From the seriousness of the responses I'm getting, it looks like this level of "compliance" is probably typical. Its annoying to think that I'm going to have to stop and analyze all their answers now to make sure they are really answering the question that was asked.
