Editors' Review Staff Feb 27, 2009
This free software accurately synchronizes a computer's clock; however, the program comes with an interface that's crowded with disabled companion programs. RocketTime is easy to use and corrects computer clock drift by checking your clock at predefined intervals. Time synchronization is based on NIST standards but the program does allow users the ability to edit which time sources to check. Other features include the ability to select time zones and a correction log that tracks the number, date, and time of each correction. The program has a useful reminder feature but it's disabled in the free version. While it's obvious this program's main purpose is to get the user to upgrade to the full version and companion suite, the free version is still useful for mobile users, anyone who needs to ensure accurate time stamps, or the user who wants to keep accurate time.
