9. 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.

10. The non-transitory, computer-readable medium of claim 9 , comprising:

transmitting, by the central server, to each of the trans-time zone sites, an indication for each of the trans-time zone sites to convert the time stamp corresponding to the target data to the time zone of the central server before transmitting the target data and the corresponding time stamp to the central server.

11. The non-transitory, computer-readable medium of claim 9 , wherein each of the trans-time zone sites is located in a different geographic region.

12. The non-transitory, computer-readable medium of claim 9 , wherein the central server receives the target data and the corresponding time stamp from each trans-time zone site in an asynchronous manner.

13. The non-transitory, computer-readable medium of claim 9 , wherein the target data is a login password shared across each of the trans-time zone sites.

14. The non-transitory, computer-readable medium of claim 9 , wherein modifying each of the time stamps from each of the trans-time zone sites further comprises determining, by the central server, the respective time zone of each of the trans-time zone sites by identifying a physical location for each of the trans-time zone sites.

15. The non-transitory, computer-readable medium of claim 9 , wherein the central server is located in a different geographical region from each of the trans-time zone sites.

16. The non-transitory, computer-readable medium of claim 9 , wherein storing the latest version of the target data includes:

replacing, by the central server, stored target data in the central server with the latest version of the target data.

17. 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.
