Launch your Actxa app and go to Account > Settings > Time Zone.
If you enable ‘Set Automatically’, it will follow your mobile device’s time zone.
If you disable it, it will stay at your native’s (i.e. Singapore) time zone.
Tap ‘Sync’ on your Dashboard to ensure that the change is reflected on both the Actxa app and Actxa Swift.
Do note that some data may be lost due to time differences.
