In various exemplary embodiments, the present invention provides transport systems and methods incorporating absolute time references, such as global positioning system (GPS) time references and/or the like, and selective buildout delays, such as first-in, first-out (FIFO) buildout delays and/or the like. In one exemplary embodiment, the transport systems and methods of the present invention are used in conjunction with the International Business Machine Corporation (IBM) Geographically-Dispersed Parallel Sysplex (GDPS) integrated, automated application and data availability solution to meet and/or exceed the associated 10 microseconds transmit/receive path differential delay requirement. Other comparable uses are also contemplated herein, as will be obvious to those of ordinary skill in the art.
