Hi

Well getTickCount was an interesting side alley since it measures in 
milliseconds - not microseconds doh! However the examples that I am seeing are 
almost certainly the elapsed time in milliseconds since system boot. The 
windows API does give a couple of calls to establish timings at this resolution 
in kernel32.dll these are queryperformancecounter which gives the count of 
clock ticks since system boot and queryperformancefrequency which gives the 
resolution of the clock. This obviously relies on the hardware having a high 
resolution clock - which my systems do. Short of attaching to the process and 
monitoring API calls it would appear that these are the calls that Oracle uses 
on MS Windows. 

If anyone is interested I can post some vb.net code which I used in my tests to 
the web.
