Delaying the server response

[benge10]

:confused;
People who enter an online competition will request a certain web page, but
the web page will not be released until an appointed time.
Up to the appointed time 1000 or maybe 10000 people may apply to enter the
competition and these requests will be held on the web server.
At the appointed time the web page will be delivered to these people.
It is important, in the interests of fair competition, that all the people
receive the web page at the same time, notwithstanding that some people may
have a slower connection than others, but this is not the servers problem, or
is it.
Is it technically feasible to achieve this, and how long would it take for the
server to burst deliver the page to these people.
Would the server have to have any special qualities to do this.
The server would maintain a database of people who have registered to use the
site, and those who have elected to play the competition.

I do this on a lot of pages using PHP, you can get the server time stamp then
use that time and compare it to the time you want the information available.
Until that time you could post some messaging to the effect of coming soon.
