Since the time on the child's device automatically adjusts based on their current location, you should generally set the Mobile Fence rules to the time zone of the country where the child resides; there is no need for parents to manually calculate time differences to adjust the rules.

For example, if you want to set the restriction time for the child's device from 10:00 PM to 7:00 AM in U.S. time, you can simply set the Mobile Fence rules to 10:00 PM to 7:00 AM as well.

However, since activity timeline records are displayed based on Korea Standard Time (KST), if you wish to view them in the local U.S. time zone, you can change the local time setting in the Mobile Fence settings menu.
