date may not occur between receiving both objects. The objects must be received by
the device on the same day.
The device has an integrated real-time clock. Therefore, time keeps on running inter-
nally and can be sent to the bus, even when no GPS coverage is available or no time
object has been received for some time. The internal clock can show a time drift of up
to ±6 seconds per day.
