Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0035] First, before specifically introducing the technical solutions of the embodiments of the present disclosure, the technical background or technological evolution context of the embodiments of the present disclosure will be introduced. Usually, in the field of time calibration, the current technical background is: the system time of electronic equipment is affected by its own performance and the environment in which it is located. As the usage time increases, the system time will deviate from UTC. Therefore, electronic equipment needs Time calibration is performed fro...

Abstract

The invention relates to a time calibration method and device, electronic equipment, a storage medium and a program product. The method comprises the following steps: acquiring first reference time, wherein the first reference time is time determined by other devices except a time server; determining an intermediate time difference according to the first reference time, the current system time of the current equipment and the initial time difference, wherein the initial time difference is a time difference determined according to second reference time sent by the time server and system time of current equipment; determining an effective time difference according to the intermediate time difference and a corresponding time difference threshold; and calibrating the system time of the current equipment according to the effective time difference to obtain calibration time. By adopting the method, the strong dependence of the whole time calibration method on the time server can be reduced, the influence on the calibration of the system time when the time server is unstable or abnormal is avoided, and the accuracy of the time calibration is further improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a time calibration method, device, electronic equipment, storage medium and program product. Background technique [0002] The system time of the device itself is the key information for the device to provide time-related services such as timing and billing. [0003] In order to accurately obtain the system time of the system clock in the device, the device communicates with the time server through NTP (Network Time Protocol, Network Time Protocol), and sends a time calibration request to the time server. In response to the time calibration request, the time server converts UTC (Universal Time Coordinated, Universal Standard Time) is fed back to the device, and the device determines the time difference between the device and the time server based on the received UTC and its own system time, and checks the time difference based on the time server to obtain an effective...
