Absolute Time Corrector queries NIST timeservers using Internet and then compares NIST time to the time set on host computer. If there is a disparity, Absolute Time Corrector automatically adjusts the computer's time to reflect NIST time. Once set up, the host computer can serve as a timeserver for network of any size. The host can be set to check NIST time as often or seldom as desired, and each computer in the network can likewise be set to check time on the host computer as often as deemed necessary by the network administrator.
