Problems solved by technology
However, because the standard time code signal of the standard time transmitting station is weak and the frequency of the standard time code signal is low, the volume of the antenna part of the radio time synchronization circuit is relatively large, and the volume of the timing device with automatic time synchronization function is difficult to realize. miniaturization
Moreover, indoors, due to the shielding of wireless signals, there will also be blind spots for receiving standard time codes indoors.
Further, there is a fee to receive timecode, which further drives up the cost of the timekeeping device

Description
technical field [0001] The invention relates to the technical field of time measurement, in particular to a timing device and system for automatic time adjustment using a short-distance wireless communication interface. Background technique [0002] Timing devices (eg, watches, clocks, etc.) usually require manual time checking. The existing automatic time synchronization technology is mainly radio wave time synchronization, that is, in order to realize the standard timing in different regions of the country, various countries will establish special standard time transmitting stations to transmit standard time codes in the form of broadcasting, and timing devices with radio wave time synchronization functions can be Receive the standard time code, and perform automatic time synchronization according to the standard time code. However, because the standard time code signal of the standard time transmitting station is weak and the frequency of the standard time code signal is...
