Restricting Time Zone Changes

Stop them changing the Time Zone.

If your child can manage to change the time zone on their device, then they can get around the settings you have put in place for Down Time.

Use the following steps on your child’s iPhone or iPad:

• If screen time has been enabled then you need to disable them to start.
• Go to Settings>General>Date & Time > Toggle on ‘Set Automatically’
• Now, got back into screen time and enable it.
• Then tap “Content & Privacy Restrictions” and toggle it on
• Scroll down and tap ‘Location Services’
• Go down to ‘System Services’
• Make sure that ‘Setting Time Zone’ is toggled off and then tap ‘Back’
• At the top of the ‘Location Services’ screen, check ‘Don’t Allow Changes.’  
• When you scroll down now you will notice that ‘Setting Time Zone’ is greyed out – meaning that changes can’t be made!
• Go back to Settings>General>Date & Time and you’ll see that this has been greyed out too.

If you want Apple to restore something that you think has been removed then contact them here with a feature request.

Apple do not respond to requests on here as they only moderate inappropriate posts, they do not react to requests.

Correct, this tip no longer works. Please put this back in as an option to protect kids from changing time zones. Even if I enable “no account changes”, it allows. Thank you.

I got a "Solved" from another mum but I can't test it myself.
