Method, system and program for correcting time of event trace data

摘要

To provide a method of correcting time of event trace data which is capable of correcting a deviation in starting time for collection of trace data. A difference in clock running rate between machines is obtained as a clock skew value by carrying out communications among a plurality of machines to be corrected a plurality of times and by storing operations of each operation as trace data and a required period of time for communications using trace data of a plurality of machines based on data on time when communications are performed and on a required period of time for communications. A time stamp value is corrected by using the obtained clock skew value so that operations of the time stamp coincide with each other.
