Your account time zone is always displayed in the bottom-left corner of the dashboard.
❗Keep in mind: We pull time zone data from your Apple Ads account.
When creating an Apple Ads account, you select the necessary time zone, define your ad groups' start and end times, and report metrics.
Once the account time zone is set up, you cannot change it afterward. In the same way, since SplitMetrics Acquire pulls the time zone you have specified in Apple Ads, the time zone cannot be changed on our side either.
