Environmental reception effects
The station obtains the accurate time with wireless technology. Same as all wireless devices, the reception is maybe affected by the following
circumstances:

long transmitting distance

nearby mountains and valleys

near freeway, railway, airports, high voltage cable etc.

near construction site

