Hey
I am making a quiz containg 20 questions for which i have to set the countdown
form1 contains 10 questions and form 2 contains next 10 questions and i want this quiz to be completed in 20 minutes

what should i do so that some countdown will be displayed on each form?

@meghajatana,

This is a great intro to a programming and system issue of "What time is it?" You may think your question is simple but most systems I know pull time from local time which may be in sync or not with all 20 machines.

I've seen such end in riotious responses as one clock on one machine is plus or minus seconds from the next so your system design needs to figure out if giving one person a few more seconds matters or not before you write your app.

That is, think through the time issue first and how to give all contestants the same time.
