in thread How can I keep track of the execution time of a script?
Yes, it *is* OS dependant, as I said on the first line of my reply. However you're wrong about the tick count, at least according to the Win32 manpage:
[CORE] Returns the number of milliseconds elapsed since the last
system boot. Resolution is limited to system timer ticks (about 10
on WinNT and 55ms on Win9X).
Its resolution is limited, however it is in miliseconds.
