Python time accumulates more than 24 hours and continues to accumulate

Recently, I've been working on a tool that asks for the time it takes to run the program, so I made a timer.

Found on the internet a lot of discoveries are 24-hour system, more than 24 hours will be back 0

And then, based on the 24-hour system, I modified a constant-time

If you want to display more than 24 hours in the day, you can modify the accumulated part of the Code

Python time accumulates more than 24 hours and continues to accumulate
