US Patent 7970946 Recording and serializing events

Event information with respect to events that occur at a client is recorded. A current client real time clock (RTC) timestamp at the occurrence of each event is also recorded. Each event is assigned a unique sequence identification. Event data including the event information and the associated RTC timestamp and sequence identification information are transmitted to a server. The server reconstructs at least one of: a chronological order of the events on the client and the time when each event occurred at the client.
