[CIP Sync] Time Sync object: set attribute single of attribute 18 (Domain number) might fail although valid attribute data is provided

Time Sync object: set attribute single of attribute 18 (Domain number) might fail although valid attribute data is provided.

This can happen since the received attribute data is casted to a 16bit pointer data type instead of an 8bit pointer data type. Therefore, depending what's present in the memory at that point in time, the data range check of the attribute data might fail.
