Abstract: Systems, methods, and devices of the various embodiments enable a distributed activity reporting system, such as a billing system, with geographically separated computing devices operating in different local time zones to account for time differences between the different local time zones. In an embodiment, serialized objects transported between the computing devices in the distributed activity reporting system, such as a billing system, may include indications of the local time zone of the computing device originating the serialized object. In an embodiment, the indications of the local time zone of the computing device originating the serialized object may be used to shift the dates and times in the serialized object to the local time zone of the receiving computing device when the received object is de-serialized.

Abstract: Systems, methods, and devices of the various embodiments enable off-line synchronization of an application running on a processor of a computing device.

Abstract: Systems, methods, and devices of the various embodiments enable management of time zone information among devices. A processor of a web server in a web server time zone (i.e., a first time zone) may receive a data set created at a communication device and a client time zone (i.e., a second time zone), wherein the data set includes an indication of the second time zone. The processor of the web server may parse the data sent to extract the indication of the second time zone. The processor of the web server may process the data set in the web server using an indication of the client time zone so as to simulate the client time zone in the web server, and thereby cause the data set to be processed as if it were in the client time zone.
