Fig. 2 is the flow chart of the time conversion method of across the time zone computer transmission of embodiment according to the present invention.This reality
The time conversion method for applying across the time zone computer transmission in example is realized on computer network shown in Fig. 1.Across time zone
Computer transmission time conversion method include:
Step 210, the original time zone data in the first time zone is converted into modification time zone data.
In the first communication node for being located at the first time zone, host 101 or mobile terminal 102 as shown in figure 1, by described first
The original time zone data in time zone is converted to modification time zone data, wherein in the modification time zone data, any time zone data
Indicated with nonnegative number.
Preferably, the original time zone data in first time zone is based on UTC agreement.Optionally, by the original time zone number
According to the positive integer added more than or equal to 12, so that original time zone data is nonnegative number.Optionally, by the original time zone data
In addition the positive integer between 12 and 19, so that original time zone data is nonnegative number.For example, by plus for 12, when first
7th area area Shi Dong, the time zone UTC are 07, by modifying time zone data after converting as 19.
Wherein, the first original time zone is two integers with sign symbol position, and modification time zone data is two integers, can
To indicate the first original time zone and modification time zone with 8 bits.
Step 220, time and the modification time zone data in the first time zone are sent.
Communication data is sent to the second communication node for being located at the second time zone, the communication number from first communication node
According to the time and the modification time zone data for including first time zone.For example, host 101 or mobile terminal 102 are by described
The time in one time zone and the modification time zone data, which are packaged, generates communication data packet, communication data packet by router, ISP and because
Special net is sent to server 107.
Wherein, the data communication follows ICP/IP protocol.Communication data is encryption data, to ensure that data are being transmitted across
Safety in journey.
Step 230, modification time zone data is reduced to the original time zone data in the first time zone.
In second communication node, the modification time zone data is reduced to the original time zone number in first time zone
According to.For example, the modification time zone data in communication data packet is reduced to first after server 107 receives communication data packet
The original time zone data in time zone.For example, the modification time zone data received is 19, the original time zone data after restoring is 07.
Step 240, the time in time corresponding second time zone in the first time zone is calculated.
Server 107 according to the original time zone data in the original time zone data in first time zone, second time zone with
And the time in first time zone, calculate the time in second time zone corresponding to the time in first time zone.For example, false
If the original time zone in the second time zone is 08, can be according to the original time zone data 07 in the first time zone and the original time zone in the second time zone
The time of difference and the first time zone between 08 calculates the time in corresponding second time zone.
The time conversion method of across time zone computer transmission of the invention, original time zone data and modification time zone data are all only
A byte is occupied, data volume is small, and time conversion only needs simple plus and minus calculation, and calculation amount is low, not only may be implemented to service
