Hi,
You can also do it like w3schools did on their exmaple. Create button at modal-body with onclick = myFunction(); and below that button create element 'p' with id = "demo" , if you click on button it will be show text depending on time.
Here is a my example. I modified a little. If you click on modal, it will be show text depending on time.
