Thanks a million in advance.

Hi Al

I'm not sure why your trying to use a server-side Timer on an asp.net page?
Timer's use up server resources, especially if you are telling it to sleep,
that could potentially tie up your requests. Also you cannot get an async
Timer to work with your web page in this way without doing postbacks to the
server.

I would recommend using the javascript "setTimeout " method on the client
side to create a timer to write to a control.

I think you're taking the wrong approach here. I don't think threading
is going to buy you anything, all your doing is spawining a new thread
thats going out of scope as soon as the page load event completes.

Why not use javascript to implement your timestamp? In page load issue
a RegisterClientS criptBlock("cli entScript", scriptString) call, where
your timer code is in the javascript. There are plenty of timer
javascript examples out there.
