Support other timezones for Appsflyer connector#1454

Currently , it pulls data based on UTC only, add support for other timezones

This is available. The AppsFlyer connector already supports non-UTC time zones: it forwards a per-account time zone to the AppsFlyer Pull and Master APIs, and only falls back to UTC when none is set. To use it, set the desired time zone (as a tz-database name, e.g. Asia/Kuala_Lumpur) on your AppsFlyer connection, and make sure the same time zone is configured in your AppsFlyer dashboard. Our support team can help set this on your account if needed.
