If you would like to synchronize the time of the device with the server, you will have to set the device to server mode. 

Refer to the article below: 

[BioStar 1] Connection Modes (Direct / Server)

If server mode is on, the device syncs the time with the server every 1 minute. 

If it still seems that the time is not synchronized with the server as shown in the box below, that is because the shown time isn't the actual time on the device.  

If you would like to know what the time the device is set on, you would have to press Get Device Time.

Then the correct time will be shown on the dashboard
