Hernandez wrote me about problems with rdtsc on hyper-threaded machines, which I believe, but I actually forgot until just now that I had written some paranoid safe and accurate Timer code . I mainly wrote it because of the freaking SpeedStep on my laptop, but it should be a safe timer that handles the QPC jump-back bug, and TSC oddities, etc. Basically it uses several timers, tries to use the finer grained one, and if it detects the finer one is wrong it steps down to a coarser one.
