Abstract

The present invention relates to an off-line timing apparatus, method, computer program product and electronic device, wherein the off-line timing apparatus includes a time source acquisition unit configured to acquire first time information from a satellite; a time source calibration unit configured to determine calibration time according to the first time information and calibrate the calibration time according to the satellite time and the satellite number acquired by the time source acquisition unit from the satellite according to the preset frequency in response to the fact that the off-line time service device and the satellite are in a connection state; and an off-line time service unit configured to respond to the off-line time service device and the satellite in a disconnected state, count on the basis of the calibration time and output time service time for time checking. According to the technical scheme of the invention, offline time service can be provided.

Description

technical field [0001] The invention relates to the technical field of timing. More specifically, the present invention relates to an off-line time service device, method, computer program product and electronic equipment. Background technique [0002] At present, there are mainly two methods for timing: communication channel timing and satellite timing. Communication channel timing mainly uses the Network Time Protocol (NTP) for Internet time synchronization. This method relies heavily on the Internet. This method cannot guarantee the accuracy of time in areas where the network signal coverage is incomplete or the network signal is unstable. The method of satellite timing is mainly to receive the signals transmitted by GPS satellites so as to realize precise timing around the world. However, the current satellite or communication channel online timing method needs to arrange antennas or connect to the Internet, but the system in some environments cannot meet the above two...
