PROBLEM TO BE SOLVED: To solve a problem in which it is difficult to reflect time in a guest OS into time in a host OS.SOLUTION: When configuring/running virtual computers on a computer, a time setting request or a time correction request inside a virtual computer is reflected to the real computer and other virtual computers. Necessity of the reflection and a relationship indicating whether a computer is reflecting to other computers or being reflected are managed and controlled. A time linkage function for receiving the time setting request and the time correction request/mode change request is provided in OSs of the virtual computers, a time unifying function for managing the requests in a unified manner is provided in an OS of the real computer, and these functions are linked. |
