MacDCF77 for Mac

From Martin Bestmann EDV:

You'll never need to adjust your computer's clock again ever! MacDCF77 automatically and continuously synchronizes the clock with the time signal of the caesium clock in Braunschweig, Germany. At the same time, the time server included in the network edition of MacDCF77 can synchronize any number of Macintosh computers over the network. The MacDCF77 clock is a receiver for the time signal of the official German broadcast from a long-wave transmitter near Frankfurt. This time signal is controlled by a caesium clock, one of the most accurate clocks in the world. It is, in fact, so precise that even in the worst case it will take several million years before it is off by one second. Apart from extreme precision, MacDCF77 also offers unmatched comfort and simplicity: Once you have installed the clocks and chosen the desired settings it keeps on working, literally without any intervention from you. You do not need to set it, to adjust for daylight saving time, to change batteries nothing! This emphasis on trouble-free operation is carried over to the software: Not only is it compatible with both System 7 and Mac OS 8, it also offers native support for Power Macintosh. Strict adherence to Apple's programming guidelines ensures maximum compatibility with future Macintosh models and operating system versions. MacDCF77 network edition transforms your Macintosh into a network time server without any need for additional software neither a file server nor File Sharing is required. Simply install the Chooser module on as many Macintosh computers as desired and select the time server. Perfect precision for all Macintosh clocks in your entire organization is as simple as that. MacDCF77 makes your Macintosh clock work perfectly forever.
