An operating system and a client application are executed by the processor and memory. The client application is configured to determine first and second coordinated universal time (UTC) time intervals for a first non-UTC time interval associated with a first event type and a second non-UTC time interval associated with the first event type; generate a single request for the remote activity feed server to aggregate corresponding events during the first UTC time interval and the second UTC time interval; and send the single request via a network interface to the remote activity feed server. ## Claims ### Claim 1 A client device comprising: a processor and memory; an operating system executed by the processor and memory; a network interface; a client application that is executed by the processor and memory and that is configured to: determine first and second coordinated universal time (UTC) time intervals for a first non-UTC time interval associated with a first event type and a second non-UTC time interval associated with the first event type; generate a single request for the remote server to aggregate corresponding events during the first UTC time interval and the second UTC time interval; and send the single request via the network interface to the remote server. ### Claim 2 (depends on 1) The client device of claim 1, wherein the client application is further configured to receive a single response from the remote server corresponding to the single request. ### Claim 3 (depends on 1) The client device of claim 1, wherein the client application generates the single request using hypertext transfer protocol. ### Claim 4 (depends on 1) The client device of claim 1, wherein the client application determines the first UTC time interval and the second UTC time interval by: sending a request to the operating system of the client device including the first non-UTC time interval of the first event type and the second non-UTC time interval of the first event type; and receiving a response from the operating system of the client device. ### Claim 5 (depends on 1) The client device of claim 1, wherein the first non-UTC time interval corresponds to a relative time period that is dependent upon a geographic location of the client device. ### Claim 6 (depends on 2) The client device of claim 2, wherein the client application interprets the single response and updates an event summary screen of the client application based thereon. ### Claim 7 (depends on 2) The client device of claim 2, wherein the client application interprets the single response and updates an event summary screen of the client application by updating a first count corresponding to the first non-UTC time interval of the first event type and updating a second count corresponding to the second non-UTC time interval of the first event type. ### Claim 8 (depends on 1) The client device of claim 1, wherein the first non-UTC time interval overlaps the second non-UTC time interval. ### Claim 9 (depends on 1) The client device of claim 1, wherein the first non-UTC time interval has a different duration than the second non-UTC time interval. ### Claim 10 (depends on 1) The client device of claim 1, wherein the first non-UTC time interval does not overlap the second non-UTC time interval. ### Claim 11 (depends on 1) The client device of claim 1, wherein the first non-UTC time interval has the same duration as the second non-UTC time interval. ### Claim 12 A server for aggregating events for remote client devices, comprising: a processor and memory; a network interface; an event database; an activity feed application that is executed by the processor and memory and that is configured to: receive a single request from a client device via the network interface, wherein the single request includes a first coordinated universal time (UTC) time interval associated with a first event type and a second UTC time interval associated with the first event type; aggregate corresponding events of the first event type in the event database for the client device during the first UTC interval and the second UTC interval; and generate a single response to the client device. ### Claim 13 (depends on 12) The server of claim 12, wherein the server is further configured to transmit the single response to the client device via the network interface. ### Claim 14 (depends on 12) The server of claim 12, wherein the activity feed application generates the single request using hypertext transfer protocol. ### Claim 15 A server for aggregating events for remote client devices, comprising: a processor and memory; a network interface; an event database; an activity feed application that is executed by the processor and memory and that is configured to: pre-aggregate events for a plurality of client devices by event type during time windows to generate pre-aggregated event counts; receive a single request from one of the client devices via the network interface including a first coordinated universal time (UTC) time interval associated with a first event type and a second UTC time interval associated with the first event type; generate a first count and a second count by aggregating corresponding pre-aggregated event counts during the first UTC interval for the first event type and the second UTC interval for the first event type, respectively; and generate a single response for the client device including the first count and the second count. ### Claim 16 (depends on 15) The server of claim 15, wherein the server is further configured to transmit the single response to the client device via the network interface. ### Claim 17 (depends on 15) The server of claim 15, wherein the activity feed application generates the single request in hypertext transfer protocol.
