            TimeSpan tsDueTime = new TimeSpan(1, 0, 0);
            TimeSpan tsPeriod = new TimeSpan(1, 0, 0);
TimerCallbacktime rDelegate = new TimerCallback(databaseTrensfer);
timer1[timer] = new System.Threading.Timer(timerDelegate, obj, dueTime,interval);

Why? What's the ultimate purpose of it? Using timers is generally questionable.

You can do it in combination with polling of the current time using System.DateTime.Now, http://msdn.microsoft.com/en-us/library/system.datetime.aspx[^].

Suppose you get a current time and determine that you need next event in a number of milliseconds which corresponds to 23:13:329 (minutes:seconds:milliseconds). Set a timer for this period to come to the next event at the boundary rounded by hours, and then change the timer to tick hourly. Something like that.
