Michael,

Even though I of course was aware of this, I did used fpgettimeofday to 
implement TTimer with the "ActiveNoGui" WidgetType, as I did not find 
something more appropriate in the RTL.

Of course I could try to directly read the X86's "Performance counter" 
register, but there were discussions if same would by reliable usable in 
CPU / OS combinations. I also could try to use vDSO in Linux archs (is 
that always available ?)

Of course in the end I need something that works for any CPU and OS.

At best, fpgettimeofday itself should be improved (maybe using 
"Performance counter" register if the Arch allows for or vDSO if the OS 
allows for).
