If Qustodio is causing the problem, here's what worked on my PC:(Assuming you have admin control over the application)- Right click the Qustodio icon- Select Disable Temporarily (give it 15 mins or whatever)- Change your timezone in Windows normally- Reboot just to verify that it stuck
The best way to avoid the issue, though, is to make sure you have the timezone set properly before installing Qustodio. Which I forgot to do this time.The reason Qustodio does this is that it has parental controls that govern access time windows for user accounts on the PC. (So if the user could change the timezone, they could circumvent this control.)
