Answer 2

here is an example of a Timer I use for a backup program I wrote that will start in 5 seconds after instantiating it and fire the callback (tick) every hour:

    private System.Threading.Timer AutoRunTimer; 

    private void Form1_Load(object sender, EventArgs e)
    {
        mybackups = new BackupService();
        AutoRunTimer = new System.Threading.Timer(tick, "", new TimeSpan(0, 0, 5), new TimeSpan(1, 0, 0));     
    }

    private void tick(object data)
    {
        if (DateTime.Now.Hour == 1 && DateTime.Now.Subtract(lastRun).Hours >= 1) // run backups at first opportunity after 1 am
        {
            startBackup("automatically");
        }
    }
