Hi,

I am a Flash novice and am intending to get a Flash professional to develop an application which is a trivia game that will ask questions and allow users to pick the correct answers.

The time from when a user starts a particular game to the time that they finish the game needs to be recorded by the Flash player.

As I will be giving prizes to the winners of the competition - I need the application to be **extremely accurate in the time recording process** on the clients computer by counting down the number of milliseconds that each user takes to complete a a game.

The potential issues that I am aware of regarding developing an accurate timer:  
a. Software applications and game speed adjusters designed to slow down/quicken Flash applications  
b. Speed and RAM of different computers might produce inconsistencies

\*\*Is it possible to develop a timer in Flash that is:  
i) very accurate (to millisecond level)  
ii) hack proof - ie: not able to be manipulated by software or other hacking tricks  
iii) will run consistently on different types of computers with different hardware configurations  
\*\*

- I do not want to use the server’s time because if a user has a slow connection or the server is slow this will not produce accurate results.

Your thoughts and advice will be much appreciated!!
