METHOD AND ASSOCIATED TIME MANAGER FOR MANAGING TIME RELATION BETWEEN SYSTEM TIMES OF DIFFERENT REMOTE SYSTEMS

摘要

The present invention provides a method and an associated time manager for managing a time relation between system times of different remote systems, including: at a first moment, obtaining a first value of a first system time and accessing a periodically updating reference counter to obtain a first count; at a second moment, updating the time relation by: obtaining a second value of a second system time along with a second count, and calculating a second value of the first system time by summing the first value of the first system time and an extrapolation interval calculated according to a difference between the first count and the second count. Thus, when synchronization with a first remote system ends, a fourth value of the first system time may be calculated according to a fourth value of the second system time and a previously stored time relation.
