Which is why I requested a separate function which just gives the picosecs since startup (or something).

That's what getCPUTime in System.CPUTime does.

No it isnt'. getCPUTime gives the.. uh.. CPU-time :-)

If all my program does is sleep, waiting for other programs to release some resource, then getCPUTime will return zero.

What I'm requesting is a function which gives the number of wall-clock picos seconds since startup, which could be used for all sorts of real-time simulations etc.

is this true? I always thought that is what getCPUTime was supposed to mean, a reading from the tsc on x86 machines for instance and distinct from the unix notion of 'cputime'.

hmm.. looking at the report, you are correct. hmm.. perhaps we need another function to read the tsc-equivalent on various CPUs. -- John Meacham - ⑆repetae.net⑆john⑈
