One of the way is to concate current date.

var fileName = DateTime.Now.ToString("yyyymmddMMss") + System.IO.Path.GetExtension(file.FileName);

// change file name with its extension
var fileName = Guid.NewGuid().ToString() + 
    System.IO.Path.GetExtension(file.FileName);

var uploadUrl = Server.MapPath("~/uploads");

file.SaveAs(Path.Combine(uploadUrl, fileName));
