Absolute Time Corrector (ATC) queries NIST timeservers using the Internet and then compares NIST time to the time setting of the host computer. If there is a disparity, ATC automatically adjusts the computer`s time to reflect NIST time. Once set up the host computer can serve as a timeserver to any size network. 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.

Absolute Time Corrector is a Windows 9X/NT/2000/XP/2003 program, designed to provide the exact time to local and network computers based on the time standard set forth by the National Institute of Standards and Technology (NIST).
Absolute Time Corrector queries NIST timeservers using the Internet and then compares NIST time to the time setting of the host computer. If there is a disparity, Absolute Time Corrector automatically adjusts the computers time to correspond to the correct NIST time.
The new version of the software features a lot of improvements, such as adjust hours only option and smart time server selection, improved time zone support, convenient and easy to navigate user interface, very simple LAN setup Wizard. Once set up the host computer can serve as a timeserver to any size network. 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.
This program comes with a list of about 250 tested time servers, so any user can be able choose the best time server for the fastest time access. Another advantage of Absolute Time Corrector is that it comes with full install/uninstall support and can be used by anybody. Using the software is intuitive and requires no special knowledge.
