Remoting and Windows Services

I am trying to figure how to use remoting to control a Windows Service I am writing. My service is basically just a timer that checks the current time, and waits for the right time to do some database tasks. I want to be able to use remoting to do things like update the time when event happens. Anything internal to the class seems easy to do, but if I store that time as say a DateTime variable as part of the host app instead of part of the object, what is the best way to setup that reference to the variable?

Sounds like you need to perform some IPC.
