Well, i guess it comes down to what you want it to do. The timer control that is available in C# and VB
does not work in web applications because, simply put, HTTP is a stateless protocol.
In any case, it all comes down to what you are trying to do. Unless you have some weird database scheme where page updates get placed in X database and only get moved to the production system once an hour and want the web page to move the data for you I don't see what your trying to accomplish. (This would be better set up as a Job in SQL Server anyway)
To answer your question, no, you can not use the .NET timer control in a page to count down.
