Reminder Model using SignalR in MVC4

Overview : I want to create a remainder for user input with alarm notification. I have a view Page with username and date to enter. If submission is successful, it should store in database. Using signalR, I want to trigger the reminder if client time(machine time) and user input time(server time) matches. It should give a popup window to show notification with user name and reminder time.

Explanation

Homepage

Username : textbox

Reminder date and time: textbox

Save reminder : button

User clicks save reminder, and the time get saved in the database. Show a popup with the username, when the current time corresponds with the reminder date and time using Signal R.

(To check the output, open the localhost url in two different browsers and see whether the popup is getting opened at the same time.)

This is the first time am going to use SignalR. Help me to do this and understand better.

Thanks in advance.
