Exactly fire tick event on completion of hour in C# Timer

I want the tick event to fire every hour exactly on completion of the hour. For e.g. it should tick on 8 am then on 9 am then on 10 am etc. It's simple that I need to set the Interval to 3600000.

The problem here is how should I identify when should I start the timer? I'm creating a tool which will run in system tray from the time when user will log on.

Solution

Please don't create a program that does nothing but waste memory. That's what Windows' Task Scheduler is for. Run your program every hour from such a task.

Here's a sample:

Go to Start->Programs->Accessories->Scheduled Tasks.
On the right side, click "Add Task..".
Select your executable.
Go to the Trigger tab.
Create Trigger with the following selection:

Run Daily 
Start today at 8:00 am
Repeat every 1 Hour

I'm sorry that I can't provide any screenshots since I'm running the german version of Windows 7.
