At a glance: Set or change an app-specific time zone in order to view the app's data more closely aligned with your time zone or that of your advertising partners. Understand the effect of time zone changes on the reporting of data within the AppsFlyer platform.
Why change the time zone?
The default time zone for new apps is UTC (UTC +0). If the app time zone is changed, this affects how data appears in the platform.
- Scenario: You work in a time zone that is not UTC. However, you want app data aligned to your time zone or to the time zone you selected with other partners like Facebook and Google.
- Goal: Simplify data comparisons between AppsFlyer and other networks.
- Solution: Align the time zone in the AppsFlyer platform with the other service providers you use. Accurate Daylight savings time is supported by default (not configurable).
Agencies view data using the time zone set by the app owner. Agencies can't set the time zone.
Changing the time zone
The account admin can make time-zone changes.
To change the app time zone:
- In AppsFlyer, go to Configuration > App settings.
- In Localization > Time Zone, select UTC.
- Click Save settings, then wait 48 hours.
- Go to Configuration > App settings.
- In Localization > Time Zone > select a time zone (per city/country).
- Click Save settings.
Change takes effect at the beginning of the next day at 00:00 UTC.
- October 24 at 22:00, the time zone is changed.
- October 25 at 00:00 UTC, the change takes effect.
