Patent ID: 8578201

Claim:
A method of converting a timestamp between a computing system and a subsystem of the computing system, comprising: receiving a relative timestamp from the subsystem; upon determining that a time skew has occurred based on the relative timestamp and a time base, updating the time base by operation of one or more computer processors, wherein the time base is a conversion variable for converting the relative timestamp to an absolute timestamp, upon determining that the relative timestamp is a first communication from the computing system, establishing the time base by subtracting the relative timestamp from an absolute system time, wherein the absolute system time is a time measure used by computing system and indicates when the relative timestamp was received, if the time base is updated, determining the absolute timestamp based on the relative timestamp and the updated time base, wherein the absolute timestamp is a timestamp of a time measure used by the computing system; and if the time base is not updated, determining the absolute timestamp based on the relative timestamp and the time base.
