HiClock Pro

 

The program can connect to a remote server over the internet with the exact time and display it on a custom panel that you can make look different (see previews). The time obtained is of course first converted to local time.

Even more it includes two alarms.

In addition, the program acts as a time server on the local network, so other computers do not need to have access to the Internet and can get the time from the computer on which HiClock Pro is already running.
