Though it is common to set up local time zone on GPS devices, it is not recommended, as Wialon works with data in UTC+0h time zone only. This is a mandatory requirement for correct data display in the system. So please reset time zone to UTC+0h in your device. Whereas, local time zone should be set in your Wialon account.
Yet there is an exception from the rule – GPS watch. In this case, you should set a local time zone in the device. When integrating such device type we allow for specifying local time zone in unit properties, after that Wialon will automatically adjust it to UTC+0h.
