HiClock Pro gives you an easy and thorough way to synchronize your system clock to the exact time using the Internet. It queries one of the National Institute of Standards and Technology timeservers, which then returns the correct standard time. Standard time is converted to local time and compared with the internal system time on the computer, and adjustments are made if necessary. Time check automatically after connection. The program has advanced alarm system and support skins. The professional version works like a time server in your local network.
