TTimeSync 1.5 -----Get exact current time for your PC from Internet . Time deviation exists among computers. This program can help your computer get exact current time from Internet or Intranet. The most famous time servers can be chosen and used, for example, NIST(National Institute of Standards and Technology). Time servers can also be customed. Moreover, time duration can be customed to synchronize time. The time difference between your computer and remote time server can be displayed and you can adjust your PC with the time offered by the remote time server. This program can also ping time-servers group and you can select the one with fastest speed. Besides the above functions, this program can work as a time server, providing time service for other computers. Different Internet service providers offer different network speeds, so speeds need testing to get the best time server. Through getting IP address, and testing exact speed of network, the best time service can be got. Various reasons can cause the uncertainty of Internet, such as the delay of the Internet and event-dispatch wait time; therefore, time deviation exists. However, time deviation is no more than 5 seconds under all circumstances, and in most cases is substantially less than 1 second .
