OneVue uses the account time zone for reports, scheduled events, alert team scheduling, and is the default time zone for your Sync and Notify devices. All other system data is displayed in the time zone of your computer or mobile device. Optionally, a specific time zone can be assigned to a device from its profile.
Go to Admin > Edit - your account name.
From the Time Synchronization section, update the Time Zone.
By default, set to the time zone of the account address zip code.
If a device's time zone is set to default, an update is downloaded to the device during its next check-in.
