❔ How to set a time interval in a timer ?

public string ProcessName { get; set; }
public int MaximumLifeTime { get; set; }
public int Frequency { get; set; }
public ProcessKiller(string name, int maximumLifeTime, int frequency)
{
    this.ProcessName = name;
    this.MaximumLifeTime = maximumLifeTime;
    this.Frequency = frequency;
}
public bool KillProcess()
{
    TimeSpan lifeTime = default;

    foreach (var process in Process.GetProcessesByName(ProcessName))
    {
        lifeTime = DateTime.Now - process.StartTime;
        if (lifeTime.TotalMinutes >= MaximumLifeTime)
        {
            process.Kill();
            WriteLog();
        }
    }

    return true;
}

public class Program
{
    public static int MinuteCount { get; set; }
    public static void Main(string[] args)
    {
        string name = args[0];
        int maxLifeTime = Convert.ToInt32(args[1]);
        int freq = Convert.ToInt32(args[2]);
        var killer = new ProcessKiller(name, maxLifeTime, freq);

        //Rerun the function after every "intervalTime" minute
        var timer = new System.Timers.Timer(freq * 60000);
        timer.Elapsed += (s, e) =>
        {
            killer.KillProcess();
            MinuteCount++;
            if (MinuteCount == 1)
            {
                Console.WriteLine("One minute passed !");
                MinuteCount = 0;
            }
        };
        //timer.Elapsed += Timer_Elapsed;
        timer.Enabled = true;
        timer.AutoReset = true;
        timer.Start();
        Console.WriteLine("Press any key to stop the program");
        Console.ReadKey();
    }
