Hi,

I've got a timer system that uses GetTickCount for calculate the number
ticks (in milliseconds), for timer calculations etc.

This works fine on my laptop, which is quite a good HP running XP.  But on
the target system running NT and is a lower spec PC, its not accurate at 
all;
usually timers are 10-20% longer (eg. A 15 second timer ends up being about
18).

I've tried using the performance counter as a more accurate system, but I'm
not getting very good results even on my HP.

Has anyone got any clues or ideas for a timer calculations for handling 
timers of
various lengths?

Regards,

Paul

PS.  my perception of accuracy is based on the Now() time logged in a file 
activitie (hours,mins,secs,milliseconds).
