To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components is omitted from the present disclosure.
In the B/S or C/S architecture, when the client (or browser) acquires the time of the server, there is a certain time when the data returned by the server is actually transmitted in the network, so that it is inaccurate that the client (or browser) directly uses the acquired time. In order to solve this problem, in the embodiment of the present disclosure, after the client (or the browser) acquires the time on the server, the client (or the browser) increases the time for transmitting the data sent from the server to the client (or the browser) in the network to obtain the current accurate time on the server when the client (or the browser) receives the time from the server.
A first embodiment of the present disclosure provides a time synchronization method, where the flow of the method is shown in fig. 1, and the method includes steps S101 to S104:
s101, sending a time obtaining request to a server, and recording local first time information of a client when the time obtaining request is sent.
The first time information is the local time of the client recorded by the client, and when the client sends a time obtaining request to the server, the time is recorded for use when the actual time length information of the first journey is calculated subsequently.
And S102, receiving the second time information from the server, and recording the local third time information of the client when the second time information is received.
The second time information is a response message after the server receives the time acquisition request, the server sends the second time information to the client, and the second time information is the time for sending the response message on the server. The third time information is the local time of the client recorded by the client, and when the client receives the second time information, the time is recorded for use in the subsequent calculation of the actual time length information of the first journey.
S103, determining the actual time length information of the first route according to the first time information, the second time information and the third time information, wherein the actual time length information of the first route is the time consumed by the server for sending the second time information to the client for receiving the second time information.
After the first time information, the second time information and the third time information are known, the distance time consumed when the server sends the second time information to the client and receives the second time information can be determined according to needs.
During implementation, firstly, determining the relative duration information of the first route according to the third time information and the second time information; secondly, determining relative duration information of all routes according to the first time information, the second time information and the third time information, namely calculating a time difference value between the first time information and the second time information, and then calculating a time difference value between the second time information and the third time information, wherein the calculation difference values are absolute values because the time information of the client is not determined to be faster than the time information on the server or slower than the time information on the server, and the calculated time length is one time length; then, determining the proportion value of the time occupied by the first route in all routes according to the relative duration information of the first route and the relative duration information of all routes; and finally, determining the actual time length information of the first journey according to the ratio value and the absolute time length information of all the journeys locally determined by the client. Specifically, the actual duration information of the first route may be determined according to the following formula:
the TN is actual time length information of the first route, the T3 is third time information, the T2 is second time information, and the T1 is first time information.
And S104, determining the current time information on the server according to the actual time information of the first route and the second time information.
When the client side synchronizes the time data of the server, the time information is sent to the actual time length required by the client side by the server, and then the current real time on the server when the time information sent by the server is received is determined together with the actual time length information according to the time information sent by the server. According to the embodiment of the invention, the time consumption in the information transmission process is considered, the time consumed in the transmission process is calculated through the three time information, and then the client can know the current time on the server accurately, so that the time error is reduced, and the system performance is improved.
After the client sends the time acquisition request to the server, the server may not receive the time acquisition request, or due to other network reasons, the client may not receive the current time information of the server, and therefore the client needs to detect whether the current time information exists according to preset time; if the current time information exists, the time synchronization of the client and the server is completed, and if the current time information does not exist, the time synchronization is not completed, and the client can send a time acquisition request to the server again to realize the time synchronization of the client and the server. After the time synchronization between the client and the server is completed, the obtained current time information may be sent to a display page for displaying, or the current time information may be used for other purposes, which is not described herein any more.
The following description is made in connection with the accompanying drawings and the specific examples.
The time synchronization method provided by the embodiment of the disclosure is applicable to time synchronization systems, including and not limited to systems of C/S architecture or B/S architecture.
The time synchronization method comprises the following steps, and the interaction process can be as shown in fig. 2:
201: the client sends a time acquisition request to the server, and the client records the client time when the time acquisition request is sent and determines the client time as first time, wherein the first time (namely first time information) is marked as T1.
202: the client receives time data (namely, second time information) generated by the server according to the time request, and sets the current time of the client when the client receives the time data as second time (namely, third time information), wherein the time data is marked as T2, and the second time is marked as T3. And determining the current time of the server when the client receives the time data as the target time (namely the current time information), and recording the target time as T4.
Because the server returns the time data generated after receiving the time request to the time of the client, the time of the client receiving the time data generates time delay in the network transmission process due to the information, therefore, T2 and T4 are different time points, and T2 and T4 have a time difference caused by the time delay.
203: according to the mathematical formula for calculating the delta T by the client, which is as follows, the time difference (namely the actual time length information of the first journey) from the time data sent by the server to the client after the time request is received by the server to the time data received by the client can be calculated, wherein the time difference is marked as delta T (namely TN). The current time of the server when the client receives the time data T4= T2+ Δ T.
204: and the client calibrates the time data T2 according to the time difference to obtain a target time T4. The target time T4 is displayed on a page or for other purposes.
According to the time synchronization method provided by the embodiment of the invention, the time delay time caused by network transmission and other factors of information is calculated through the time of the client when the client sends the time request, the time of the server when the server receives the time request and the time of the client receiving the data returned by the server, so that the time of the server when the client receives the data returned by the server is calculated, and the time of the client is calibrated.
If the time T1 of the client when the client sends the acquisition time request to the server is 1 hour, 20 minutes and 15 seconds, the time data T2 received by the client and generated according to the time request by the server is 1 hour, 20 minutes and 18 seconds, and the time T3 received by the client and generated according to the time request by the server is 1 hour, 20 minutes and 19 seconds. According to the formula, the time difference delta T from the time when the server receives the time request to the time when the client sends the time data to the time when the client receives the data is calculated as follows:
the client receives the time data at the current time T4= T2+ Δ T =1 hour, 20 minutes, 18 seconds +3 seconds =1 hour, 20 minutes, 21 seconds of the server.
As can be seen from the above, in the prior art, after the client sends the time obtaining request to the server, the time difference between the time data returned by the server and received by the client is 3 seconds, which indicates that according to the time synchronization method in the prior art, if the transmission time of the information in the network is long, a huge deviation is caused to the server time obtained by the client. According to the scheme of the embodiment of the disclosure, the server time received by the client can be corrected, the time error is reduced, and the effect of time synchronization accuracy between the client and the server is further improved.
The time synchronization method of the embodiment of the disclosure comprises the following steps: the client sends a time acquisition request to the server and determines the client time of the time acquisition request sent by the client as a first time; the client receives time data generated by the server according to the time request, and determines the current time of the client as second time when the client receives the time data, wherein the time data represents the current time of the server when the server receives the time acquisition request; the client calculates according to the first time, the time data and the second time to obtain a time difference from sending the time data to the client after the server receives the time request to receiving the time data by the client, wherein the time difference is used for representing the time length of the client or the operation time length of the server when the server sends the data to the client and the client receives the data; and adding the time data and the time difference to obtain target time, wherein the target time is used for representing the current time on the server when the client receives the server data. During implementation, calculating according to the first time, the time data and the second time to obtain a time difference; summing the time data and the time difference to obtain target time; and calculating according to the time data and the time difference, and sending the target time to a display page for displaying after the target time is obtained, or using the target data for other purposes.
When the time synchronization operation is performed on the client and the server, checking whether the time synchronization operation is performed; determining a preset interval duration when the execution of the time synchronization operation fails; and performing time synchronization again after the preset interval duration is reached.
When the time difference value is calculated, the time data can be converted into a timestamp mode which is easier to calculate; and when the time difference value is calculated, the absolute value of data obtained by subtracting the time data is taken, wherein the absolute value is mathematical expression and represents that the difference between two numbers is a non-negative number.
A second embodiment of the present disclosure provides a time synchronization apparatus, a structural schematic of which is shown in fig. 3, including:
the sending module 10 is configured to send a time obtaining request to the server, and record local first time information of the client when the time obtaining request is sent; the receiving module 20 is coupled to the sending module 10, and is configured to receive the second time information from the server, and record third time information local to the client when the second time information is received; a first determining module 30, coupled to the receiving module 20, configured to determine actual duration information of the first route according to the first time information, the second time information, and the third time information, where the actual duration information of the first route is time consumed by the server to send the second time information to the client and receive the second time information; and the second determining module 40 is coupled with the first determining module 30 and is used for determining the current time information on the server according to the actual duration information of the first journey and the second time information.
The first time information is the local time of the client recorded by the client, and when the client sends a time obtaining request to the server, the time is recorded for use when the actual time length information of the first journey is calculated subsequently.
The second time information is a response message after the server receives the time acquisition request, the server sends the second time information to the client, and the second time information is the time for sending the response message on the server. And the third time information is the local time of the client recorded by the client, and when the client receives the second time information, the time is recorded for later use when the actual time length information of the first route is calculated.

The first determining module is specifically configured to determine the actual duration information of the first route according to the following formula:
and TN is actual duration information of the first route, T3 is third time information, T2 is second time information, and T1 is first time information.
