The PTB (physical technological Federal Institute) among others offers two time servers. For the automatic synchronization of the system time the Z-Cron Scheduler and others can query for these time servers on the Internet and can synchronize the Windows computer of its own when required exactly with the respective nuclear time seconds.

The Z-Cron program queries for the respective time server over port 37 by TCP/IP and sets the computer watch provided that necessary.

The time servers predefined in Z-Cron for the time synchronization, be able to also to change when required, in which you simply to create a text file with the name ntpserver.txt in the program directory of Z-Cron.
