Editors' Review

Sidereal Clock is a tiny application that allows users to keep track of local mean sidereal time. The program does function appropriately, but its complete lack of other features or options may be disappointing to some users.

This program may well be the smallest and simplest program we've ever reviewed. Users can enter their time zone or have the clock detect it automatically, and users can also enter their longitude. But that's it. The clock is small, about 1 inch by 2 inches, and displays sidereal time in hours, minutes, and seconds. An online Help file gives a brief description of each of the clock's features. Users access the program's settings by right-clicking on the clock's face, and it may seem at first that the program contains several other features, including the ability to display universal time and use a calculator and alarms. However, attempting to access these features results in a message encouraging users to upgrade to the commercial version of the program. If you truly need a sidereal clock and nothing more, this program is fine. But if you're looking for features of any sort, you're better off with something else.

Sidereal Clock is free. It comes as a ZIP file but installs and uninstalls without issues. We recommend this program to all users seeking a very basic way to keep track of sidereal time.
