Description

A device time synchronization method and device

technical field

The present invention relates to the field of communication technologies, in particular to a device time synchronization method and device.

Background technique

In the field of communication technology, as users (including end users and operators, etc.) have higher and higher requirements for localization, product localization has become an important link in product development. The client and server of the product must not only Support single-region deployment and access, and also need to support cross-region deployment and access.

When the server and the client are deployed in different time zones, when each client submits time information to the server, it needs to convert it into a unified time reference with the server, that is, the time in the time zone where the server is located or UTC (Coordinated Universal Time, Coordinated Universal Time or Coordinated Universal Time). Similarly, when the server pushes the time information to each client for display, it needs to be converted to the local time of each client according to the time zone where each client is located.

In areas where daylight saving time is implemented in some regions, such as Europe or the United States, the above conversion needs to consider the rules of daylight saving time. Usually, daylight saving time rules are built into the server device and client device operating systems or underlying platforms. In practical applications, it is found that the update frequency of the daylight saving time rules of the client and the server may be different. When the daylight saving time rules of the client and the server are inconsistent, it will cause an error in the time conversion between the client and the server.

Taking a typical product with a browser/server (B/S) structure as an example, under this application structure, the browser serves as the client, and the server is usually a Java-based application platform. In this scenario, daylight saving time rules are built into the client operating system and the Java virtual machine of the server respectively. Once the Java virtual machine version of the server is determined, it will generally not be updated, so the corresponding daylight saving time rules will not be updated either. The client browser may run in various heterogeneous systems, such as: mobile operating system, Windows XP, Windows VISTA, Windows7, etc., and there may be daylight saving between these systems running on the client and the Java virtual machine on the server. Inconsistencies in the time rules lead to errors in the time conversion between the client and the server, thus affecting the correct operation of the system.

Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

First, a device time synchronization method provided by the present invention is introduced, which can be applied to devices with a B/S structure.

Referring to FIG. 1, the process of an embodiment of a device time synchronization method provided by the present invention may specifically include:

Step 101, the server device receives the time reference information on the client device sent by the client device, wherein the client device and the server device are in different time zones.

In the embodiment of the present invention, during the data transmission process between the client device and the server device, a time synchronization operation needs to be performed, that is, there is data information interaction between the client device and the server device, and the server device sends data to the client The time information carried by the end device when sending session data should be consistent with the time information carried by the client device to the server device. However, since the client device and the server device are in different time zones, the client device and the server The time base on the device may not be synchronized, therefore, different time information may be set for the same session between the client device and the server device.

In order to ensure the synchronization of time information between the device client device and the server device, in this step, the client device sends the time reference information on the client device to the server device, so that the server device The local time information is synchronized with the time reference information on the end device.

Step 102, when the server device has a session with the client device, synchronize the local time information of the server device according to the time reference information.

In this step, when the server device conducts a session with the client device, it needs to synchronize local time information according to the time reference information.

The server device synchronizes the local time information so that the time reference on the server device is consistent with the client device, so that the server device receives the session sent by the client device or sends a message to the client device. When the above-mentioned client device sends a session, both devices maintain a unified time reference.

It can be seen that in the embodiment of the present invention, the client device and the server device conducting the session are in different time zones, and the client device sends the time reference information on the client device to the server device, and the server device Synchronize the local time information with the above time reference information. Since the client device and the server device use the same time reference, the client device and the server device can carry synchronized time information when transmitting information to each other, and can avoid time conversion errors caused by different time reference information.

On the basis of the above embodiments, when the server device needs to send session data to the client device, as shown in Figure 2, the following steps may also be included:

Step 103, the server device sends session data to the client device, the session data carries time information of the server device, and the time information of the server device is synchronized to all time information of the client device.

In step 103, when the server device sends session data to the client device, usually, the session data carries the time information of the server device. In the embodiment of the present invention, since the server device The time reference information on the client device is stored, therefore, before the session is sent, the time information of the server device carried in the session data can be synchronized to the client device according to the time reference information time information.

In the embodiment of the present invention, after the client device acquires the session data, since the session data carries time information synchronized with the client device, the client device does not need to perform time conversion, that is, The session data can be obtained correctly.

Specifically, the time reference information may be daylight saving time reference information. This is because clients and servers in different time zones may have different rules for their own daylight saving time. Whether and when daylight saving time is implemented is determined by each country. As time changes, the regulations may also be adjusted. Once daylight saving time When the time rules are adjusted, the client and server may be updated out of sync, resulting in different rules for the client device and server device for daylight saving time.

In the embodiment of the present invention, the daylight saving time reference information may specifically include: time zone offset, time zone identifier, daylight saving time start and end information, and the daylight saving time start and end information is, for example: daylight saving time start month, daylight saving time Start date, DST start time, DST end month, DST end date, DST end time and other information. In addition to including the time zone identifier and the time zone offset, the accuracy of synchronizing the daylight saving time information between the client device and the server device can be improved by carrying other daylight saving time reference information parameters.

Therefore, as shown in FIG. 3, in the above step 102, the server device synchronizes local time information according to the time reference information, and the specific implementation method may be:

Step 302: The server device establishes DST time information corresponding to the client device according to the time zone object, and the DST time information corresponding to the client device is adjusted according to the DST reference.

Usually, in the B/S structure, the same server device may establish communication connections with multiple client devices at the same time, therefore, the same server device can have sessions with multiple client devices at the same time. In the embodiment of the present invention, when the server device and multiple client devices are in different time zones, if each client device conducts a session with the server device, the server needs to use the time reference information sent by the current client device When synchronizing the local time information of the server device, when the server device is in conversation with multiple client devices at the same time, the server device cannot know which client device should send the time reference information as the standard, The time information synchronization on the server device is confused.

In order to avoid the above-mentioned defect, in the above-mentioned embodiment, the server device establishes a time zone object corresponding to the client device according to the daylight saving time reference information, and the time zone object includes the time zone where the client device is located Daylight saving time benchmark information for . In this implementation manner, there is a one-to-one correspondence between the time zone object established on the server device and the client device. When there are multiple client devices in different time zones, a corresponding number of time zone objects are established on the server device.

The time zone object of the client device, and the time zone object carries the daylight saving time reference information of the time zone where the client device is located. Therefore, the server device establishes DST time information corresponding to the client device according to the time zone object, and the DST time information corresponding to the client device is adjusted according to the DST reference. In the server device, corresponding to multiple client devices in different time zones, respectively establishes DST time information corresponding to the client devices, so that the server device maintains time synchronization with the multiple client devices respectively.

When the server device needs to send session data to a certain client device, the server device needs to first obtain the time zone object corresponding to the client device, and then, according to the time zone object, in the server device The daylight saving time information of the corresponding session is established on the Internet; the daylight saving time information of the corresponding session may include: the time information when the server device sends the session. Afterwards, the server device sends session data to the client device, and the session data carries the daylight saving time information when the session occurs.
