Timing

[Nick]

I have a client who is building an internal questionaire for their
employees. However the twist is that they wish to time the user
*accurately* in how long they actually take to do the test. I have been
further instructed to make the timing solution hidden as much as possible -
so it cannot be hacked. Has anyone got any ideas on how I could implement
this?

Nick.

Sure. Get the current time when the user requests the first page of the
questionnaire, and store it somewhere (database, Session, etc). When they
post the last page, get the current time again, and subtract the first time
from it.

You could pass a cookie with the time when the click the "Start" button and
then retrieve the cookie when they click the "Done" button. After that it is
just difference calculation.

To make it really hidden, use a Session variable.

Hi Kevin, I had thought about that but I wasnt sure if it would be accurate
enough. For example, because these times are so important, if two people
actually have the same times but the server lags in dealing with a POST from
one of them, it would seem they were slower when it was the server itself
that was the problem. Mayeb I shouldnt worry about that though...

Thanks for replying.

Well, you're talking about at most a few seconds.
