Each embodiment be explained in detail.However, it will be understood by those skilled in the art that in each embodiment party of the present invention
In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details
And various changes and modifications based on the following respective embodiments, it can also realize the application technical solution claimed.
The first embodiment of the present invention is related to a kind of method for synchronizing time, it is applied to be used as from node in distributed system
Distributed Application.Specifically, distributed system includes multiple Distributed Applications, each Distributed Application is deployed in a machine
On device (such as server or terminal), there will be the distribution for configuring parameter management function in the present embodiment in distributed system
Application settings are host node, other Distributed Applications are set as host node；It is same that the time is each carried out from host node from node
Step.Figure 1A and Figure 1B are please also refer to, Figure 1A is the flow chart of the method for synchronizing time of the present embodiment, wherein time synchronization side
Method includes time difference calculating process (step 101 to step 103) and synchronizing process (step 104 and step 105)；Figure 1B is the time
The schematic diagram at each time point in synchronous method.
Step 101：It obtains and asks to host node sending time, and record the local sending time of time acquisition request.
That is, host node provides time interface to respectively from node calling.It obtains and asks from node to host node sending time, and
And the local sending time T1 of request is obtained from the nodes records time.Wherein, local sending time T1 refers to sending to be somebody's turn to do from node
Time obtains when asking from the system time on machine where node.
Step 102：The master time of host node feedback is received, and records the local reception time of master time.
Wherein, host node upon receiving a request, can feed back to the time (master time) of itself from node, from section
Point receives the master time of host node feedback；That is, the master time of host node feedback is when feeding back the host node at moment
Between T2.The local reception time T3 of master time is also recorded from node；Wherein, local reception time T3 refers to receive from node and be somebody's turn to do
From the system time on machine where node when the master time at feedback moment.
Step 103：According to local sending time, the local reception time and feed back the moment master time, calculate from
Node is with host node in the time difference for feeding back the moment.
Wherein, feedback the moment slave node local zone time T4 (i.e. feed back the moment slave node time T4) can be with table
It is shown as T4=(T1+T3)/2；Then D=can be expressed as in the master time at feedback moment and the time difference D from node time
T2-T4=T2- (T1+T3)/2.It is stored in from the memory of node from node by the time difference, for making when subsequent synchronization processes
With.
Step 101 as above is to 103 being time difference calculating process.Although time difference D herein is directly anti-from calculation formula
What is answered is master time and the time difference from node time at the feedback moment, still, it is however generally that, machine where host node
System time and the system time of machine where the node be considered at the uniform velocity timing, then time difference D
Master time and the time difference from node time at any one time can be characterized.
Preferably, the slave node in the present embodiment can periodically repeat the time difference calculating process, with periodically more
The new time difference.Update cycle can be set as needed, such as the update cycle can be set to 5S；Then think at least one
In a update cycle, the system time of machine where host node and the system time from machine where node are at the uniform velocity timing
, which can be as the master time of any moment in this period and from the time difference of node time；Wherein more
Newly cycle set is smaller, and time difference update is more frequent, and the calculated time consistency of subsequent synchronization processes can be made better.
Step 104：Obtain the local zone time at current time.
Specifically, when needing to obtain synchronization time in business processing from node, into synchronizing process.It is obtained from node
Take the local zone time T5 at current time, wherein the local zone time T5 at current time refers to current time from machine where node
System time.
Step 105：According to the local zone time at current time and time difference, calculates the master time at current time and incite somebody to action
Its as from node current time synchronization time.
By step 103 it is found that at any one time, master time-is from node time=time difference, therefore, a period of time in office
It carves, master time=from node time+time difference；That is, the master time T6 at current time can be expressed as, T6=T5
+ D=T5+T2- (T1+T3)/2；I.e. using the master time at current time as from node current time synchronization time；And
The synchronization time at the current time is applied to business processing.
As above step 104,105 are synchronizing process.Wherein, in the time difference calculating process in the present embodiment, the time difference=
Master time-is from node time；Right the present embodiment is not intended to be limited in any this, in other examples, can also, the time difference=
From node time-master time, i.e., in step 103, time difference D=T4-T2=(T1+T3)/2-T2, corresponding, step 105
In current time master time T6=T5-D=T5- (T1+T3)/2+T2；It is found that different modes, finally calculates
Result (the master time T6 at current time) be identical, only calculating process is slightly different.
It should be noted that in the present embodiment, time difference calculating process can be periodically carried out from node, with periodically
The time difference is updated, and the when of obtaining synchronization time is being needed to enter synchronizing process；Right the present embodiment is not intended to be limited in any this；
Can also be entry time difference calculating process and synchronizing process from node when needing to obtain synchronization time in other examples.

The time difference of the master time of host node feedback).It can be preset there are one time threshold from intra-node, judge to ask duration
Whether L is more than the time threshold, if it does, indicating that request duration has timed out, then it represents that the master at the feedback moment this time obtained
Node time is invalid, can retransmit time acquisition request；If had not timed out, this data (local hair can be used
Send time, local reception time, the master time for feeding back the moment) calculate the time difference.Wherein, time threshold can be according to reality
Situation is set, for example, it can be set to being 10 milliseconds.
