Patent ID: 8001076

Claim:
A ranging time stamp synchronization method comprising: computing a time range for a specified time; producing time stamp synchronization anchors using said time range for each of said anchors; computing a drift value for said time range; wherein said drift value is computed as a difference between a mean time of a current synchronization time stamp and a previous synchronization time stamp divided by an actual elapsed time in between producing said current synchronization time stamp and said previous synchronization time stamp; repeating said computing a time range for a specified time step and said producing time stamp synchronization anchors step when said drift value exceeds a threshold; and, using said anchors to update data items in a remote data source in a remote host computing platform with data items from a primary data source in a primary host computing platform when a time stamp of each of said data items from a primary data source falls within a range defined by a minimum time of a last time stamp synchronization anchor and a maximum time of a next time stamp synchronization anchor.
