Fig. 1 is disclosed in this invention for router side access equipment and the inconsistent system for prompting of internet time Configuration diagram.As shown in Figure 1, user uses mobile phone or apparatus such as computer access router, router and time server Between by Network Time Protocol by the time coordination of equipment to UTC.
Fig. 2 is router side access equipment disclosed in this invention and the flow of the inconsistent based reminding method of internet time Schematic diagram.As shown in Fig. 2, the method for the present invention includes:
Step 201, when router receives the access of equipment, NTP messages are sent to time server.
In this step, user use mobile phone or apparatus such as computer access router, router using Network Time Protocol to when Between server send NTP messages.
Specifically, NTP forms are as shown in figure 3, including following field:
LI:Jump indicator, alerts in the approaching boudoir second of the insertion of final moment of of that month last day;
VN:Network Time Protocol version number;
Mode:Pattern, the field include values below:0- is reserved;1- symmetrical behaviours;3- client computer;4- servers; 5- is broadcasted;6-NTP controls information;
Stratum:The entirety of local clock rank is identified;
Poll:Signed integer represents the largest interval between continuous information;
Precision:Signed integer represents local clock accuracy;
Root Delay:There is the total delay that symbol fixed point serial number represents Primary Reference source, the position 15 in very short time is arrived Waypoint between 16;
Root Dispersion:No symbol fixed point serial number represents the normal mistake relative to Primary Reference source, very in short-term Waypoint between interior position 15 to 16;
Reference Identifier:Identify special reference source;
Original time stamp (Originate Timestamp):It it is the time that separation client computer is asked to server, using 64 Position markers (Timestamp) form;
Receiving time stabs (Receive Timestamp):It it is the time for asking to reach client computer to server, using 64 Markers form;
Delivery time stabs (Transmit Timestamp):It it is the time that separation server is replied to client computer, using 64 Position markers form;
Authenticator(Optional):When realizing ntp authentication pattern, primary identifier and message digit domain are just Including defined message authentication codes (MAC) information.
Step 202, judge whether to receive the NTP messages that time server returns, if so, carrying out step 203;If It is no, then terminate this flow.
In this step, the specific form of NTP messages of return is as before, repeat no more.
Step 203, network time is obtained.
In this step, Internet has multiple time servers, and the time source that time server obtains UTC can be Atomic clock, observatory, satellite etc., therefore, time server have accurate and reliable time source.
Router carries out NTP back messages parsing and obtains network time, and detailed process is as follows:
Router sends a NTP messages to time server, and the NTP messages are in Originate Timestamp fields With timestamp when leaving router, which is first time T1.
When this NTP message arrival time server, time server is in the Receive Timestamp words of NTP messages The timestamp of arrival time server is added in section, which is the second time T2.
When this NTP message time departure server, time server is in the Transmit Timestamp words of NTP messages The timestamp of time departure server is added in section, which is third time T3.
When router receives the NTP messages, the local zone time of router is the 4th time T4.
So far, router has possessed enough information to calculate two important parameters:
Round-trip delay Delay=(T4-T1)-(T3-T2) of NTP messages.
The time difference offset=((T2-T1)+(T3-T4))/2 of router relative time server.
Router is generally connected with multiple time servers, can be selected most according to the round-trip delay Delay of NTP messages Good path and source determine the time server time.
According to the time difference offset of router relative time server, when router gets network time, i.e. network Between=the time difference offset of time server time+router relative time server.
The network time that router parses is preserved with timestamp form, as from 01 month 1970 01 Greenwich Mean Time When day 00 00 divide 00 second to present total number of seconds.
Step 204, the local zone time of current accessed equipment is obtained.
In this step, the local zone time of current accessed equipment is parsed by the function of time of browser, and will be current The local zone time of access equipment is preserved with timestamp form.
Step 205, the local zone time of network time and current accessed equipment is compared, if network time and current accessed are set Standby local time difference is more than or equal to pre-set threshold value, carries out step 206;If network time and current accessed equipment Local time difference be less than pre-set threshold value, then terminate this flow.
The prior art is compared to, in the present invention, router pre-sets time difference and calculates function and call alert Function, when equipment is by browser access router, router allocating time mathematic interpolation function calculates network time and works as The local time difference of preceding access equipment, and decide whether to call prompting (alert) function pop-up dialog box according to difference User is prompted to calibrate the local zone time of current accessed equipment.
Step 206, the local zone time of prompting calibration current accessed equipment.
In this step, if the local time difference of network time and current accessed equipment is more than or equal to pre-set Threshold value, such as 60 seconds, then the prompting of calibration local zone time is sent to current accessed equipment.
Compared with prior art, prompting of the present invention when router side is realized when access equipment and inconsistent network time Function reminds user's calibrator (-ter) unit time by the way of active, is found so as to avoid user's going passively, reduces equipment The possibility being had an impact to user is not allowed in time.
