As we can see, the values are shown in decimals. We need to format them to get our final result.

Step 3

Now select the generated values and right-click, then select format cells to open a pop-up window. In the pop-up, click on "Custom" and enter the type as dd:hh:mm:ss, then click "OK" to complete our process.
