In what way do the results change? What compiler, OS, and motherboard
chip set do you have - see MS Knowledgebase article Q274323.
There was a problem with certain chipsets and MS Windows that caused
the machine clock to appear to jump forward 2**24 ticks (several seconds)
if you did multiple clock reads with less than several microseconds
between them. Gnat 3.15 fixed that, but introduced a new clock error,
which I reported and they say they've fixed for future versions. Janus
has a version with the fix, but I don't know about other compilers.
