fpGetTimeOfDay is used to implement Now(). This should not be changed.
Why not, If there are better ways ?
I did a quick search in the RTL sources and found that there is
"GetTickCount64" that maybe could be used as a central cross-platform
function to implement certain timing stuff (including NOW).
Right now this is not the case. fpGetTimeOfDay is called in several
other locations. I suppose, here GetTickCount64 could be used.
Depending on "HAVECLOCKGETTIME" GetTickCount64 just calls fpGetTimeOfDay.
In - more advanced ? - archs. GetTickCount64 calls "clock_gettime".
In my X86 32 Bit Linux it indeed does call clock_gettime.
But this again is just a system call and so I suppose it does not help
to improve performance.
