The structural representation that Fig. 2 is the system of a kind of synchronization server time in the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is further described.
Shown in Figure 1, the method for a kind of synchronization server time of the present invention comprises the following steps:
Step S101, obtain the current server time as request transmission time (being designated as T1), and be connected with SOCKET between terminal by the server set up in advance the described request transmitting time is sent to described terminal with the form of message, then enter step S102.
Step S102, receive the message that described terminal is fed back, and obtains the current server time as response time of reception (being designated as T2), and the message of described feedback is resolved, and then enters step S103.
It should be noted that, the major part operation (step S101 described above, step S102 and follow-up step S103, step S104 etc.) in the embodiment of the present invention is all carried out in server.But, as an embodiment preferably, after step S101 sends to described terminal by the described request transmitting time with the form of message, before step S102 receives the message that described terminal fed back, can also comprise the step of carrying out as follows in terminal:
Step S1011, terminal is obtained current terminal time as request receiving time (being designated as T3), and the described request time of reception is changed after receiving the message of server transmission, joins in former message, then enters step S1012;
Step S1012, obtain current terminal time as response transmitting time (being designated as T4), described response transmitting time is changed, joined in former message and (now in message, had three time value: T1, T3, T4), obtain the message of described feedback and send to described server.
As an embodiment preferably, the process of obtaining current terminal time in described step S1011 and step S1012 specifically can comprise as follows: by the GPS(Global Positioning System of described terminal, global positioning system) module obtains the standard time as current terminal time.
Step S103, supplement value (being designated as t) according to analysis result and the clock of described response time of reception calculation server time and terminal time, then enters step S104.
As an embodiment preferably, calculate according to analysis result and described response time of reception the process that described clock supplements value in this step and specifically can comprise as follows: the request transmission time T1 obtained after being resolved according to described response time of reception T2 and to the message of described feedback, request receiving time T 3, respond transmitting time T4 and calculate the supplementary value t of described clock.
Concrete computational process is as follows: suppose that d is the server and client side two-way time, t is the time deviation between the server and client side (being the supplementary value of clock), has:
T3=T1+t+d/2；T3-T1=t+d/2；T2=T4-t+d/2；T2-T3=t-d/2；
Can release: d=(T2-T1)-(T4-T3); T=((T3-T1)+(T4-T2))/2;
Because T1, T2, T3, T4 are known, therefore by above-mentioned formula, can calculate clock and supplement value t.
Step S104, supplement value according to described clock and carry out the synchronous of server time.Concrete, calculate the supplementary value t of clock in step S103 after, call following system function and can realize the synchronous of server time:
Server standard time=current server time T 2+ clock is set and supplements value t.
As an embodiment preferably, for fear of operate miss, guarantee the accuracy of server time, step S103 calculate described clock supplement value after, step S104 according to described clock, supplement value carry out server time synchronously before, can also comprise the steps:
Step S1031, repeat abovementioned steps (comprising step S101-step S103), the clock that calculates predetermined number supplements value (as calculated continuously 5 t or 10 t etc., concrete number can be made different the setting according to different situations), and average and carry out the synchronous of server time as the supplementary value of final clock.
As an embodiment preferably, after carrying out server time synchronous, step S104 can also comprise the steps:
Step S105, transmission is closed the request of SOCKET connection to described terminal, and closes described SOCKET connection after the response that receives described terminal.Closing server is connected with the SOCKET between terminal in time, can save system resource.
Finally, consistent with the height of standard time in order to guarantee server time, we can also setup times synchronizing cycle, repeat above-mentioned steps S101-step S105 when the cycle arrives, in order to get the most accurate server time.
Corresponding with the method for above-mentioned a kind of synchronization server time, the present invention also provides the system of a kind of synchronization server time, comprises server end, and as shown in Figure 2, described server end comprises:
Clock supplements value computing module 103, for according to analysis result and the clock of described response time of reception calculation server time and terminal time, supplementing value;
Synchronization module 104, carry out the synchronous of server time for supplement value according to described clock.
As an embodiment preferably, the system of synchronization server time of the present invention can also comprise terminal, and described terminal comprises:
The first message modular converter, after the message that receives described server end transmission, obtain current terminal time as the request receiving time, and the described request time of reception changed, and joins in former message;
The second message modular converter, for obtaining current terminal time as the response transmitting time, changed described response transmitting time, joins in former message, obtains the message of described feedback and send to described server end.
As an embodiment preferably, described terminal can also comprise: the GPS module, for obtaining the standard time;
Described the first message modular converter, the second message modular converter obtain the standard time as current terminal time by described GPS module.
As an embodiment preferably, described clock supplements after value computing module can be resolved according to described response time of reception and to the message of described feedback the request transmission time, request receiving time, the response transmitting time that obtain and calculates the supplementary value of described clock.
Other technical characterictic of the system of above-mentioned a kind of synchronization server time is identical with the method for a kind of synchronization server time of the present invention, and it will not go into details herein.
