Method and device for data version comparison between trans-time zone sites

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• receiving, by a central server from a plurality of trans-time zone sites, target data and a corresponding time stamp from each trans-time zone site, wherein each of the time stamps is based on a respective time zone of a sending trans-time zone site from which the target data and the time stamp were received, wherein the trans-time zone sites are international sites of a cross-border payment service;
• modifying, by the central server, each of the received time stamps based on the respective time zone of the sending trans-time zone site for the time stamp and a time zone of the central server;
• subsequent to receiving the target data and the corresponding time stamps, comparing, by the central server, the received target data from each trans-time zone site to the received target data from another trans-time zone site of the plurality of trans-time zone sites based on the modified corresponding time stamps;
• aggregating the received target data from each of the trans-time zone sites in a version order corresponding to an order of the modified corresponding time stamps;
• and
• storing, by the central server, a latest version of the target data having a modified corresponding time stamp that indicates a later time than each of the other modified corresponding time stamps.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• receiving, by a central server from a plurality of trans-time zone sites, target data and a corresponding time stamp from each trans-time zone site, wherein each of the time stamps is based on a respective time zone of a sending trans-time zone site from which the target data and the time stamp were received, wherein the trans-time zone sites are international sites of a cross-border payment service;
• modifying, by the central server, each of the received time stamps based on the respective time zone of the sending trans-time zone site for the time stamp and a time zone of the central server;
• subsequent to receiving the target data and the corresponding time stamps, comparing, by the central server, the received target data from each trans-time zone site to the received target data from another trans-time zone site of the plurality of trans-time zone sites based on the modified corresponding time stamps;
• aggregating the received target data from each of the trans-time zone sites in a version order corresponding to an order of the modified corresponding time stamps;
• and
• storing, by the central server, a latest version of the target data having a modified corresponding time stamp that indicates a later time than each of the other modified corresponding time stamps.
