How to increase Timer.Interval timer period?

Question

C++ / C#

Hello colleagues. I use a timer in the program

timer1 = new System.Windows.Forms.Timer();
timer1.Interval = int.Parse(stringSettins[6]) * 1000; // 1 800 000 - 30 минут 600 000 - 10 минут
timer1.Tick += timer1_Tick;
timer1.Enabled = true;

The jamb is that timer1.Tick is of type INT, respectively, I can’t set an interval of more than 30 minutes. And I need an interval of 3-5 hours.
What to do?

Answer 1

void Start<T>(T interval)
{T time =0;
while(time <interval){Thread.Sleep(1);time++;}
TickEvent();
}
Something like this.
