Create method for 24 hour time format

[AnonymousDev100]

Important Note: I am not allowed to Use TimeSpan

I am trying to create C# method with two int arguments

public void Time(int hours, int minutes)

which satisfies all the following Test Cases:

Time(11, 7), returns: "11:07"
Time(24, 0), returns: "00:00"
Time(26, 0), returns: "02:00"
Time(0, 160), returns "02:40" (since 160 minutes = 2 hours and 40 minutes)
Time(-1, 0), returns: "23:00" (negative number - counterclockwise)
Time(1, -40), returns: "00:20"
Time(-25, -160), returns: "20:20"

Here is an example that does not use any time-related functions.

            int h_div, h_rm, m_div, m_rm, i = 0;
            while(minutes < 0){
                minutes = minutes + 60;
                i++;
            }
            hours = hours - i;
            while(hours < 0) hours = hours + 24;
            m_div = Math.DivRem(minutes, 60, out m_rm);
            h_div = Math.DivRem(hours + m_div, 24, out h_rm);
            Console.WriteLine(String.Format("{0:D2}:{1:D2}", h_rm, m_rm));

You can use DateTime and a one-liner:

int hours = -25;
int minutes = -160;
 
string textTime = DateTime.Today.AddHours(hours).AddMinutes(minutes).ToString("HH:mm");
 
Console.WriteLine(textTime);
