PYTHON IF ELIF DATETIME, what's the error in my datetime code? Works if i rerun the code but if i let it run normaly, the hours updated gimme a 24h

On my code, the label lb1 should be updated everytime it reaches the time target that shows if the bot is running and the time left until it stops, and if its not running shows the time left until it will start. Works normal if I stop the code and run again when the time hit the target, but if i don’t stop, instead of showing me the time left until the next target, it shows me an 24 hours or 14 hours countdown in the label. What am i doing wrong?
Here’s the full source code:
