Check your system clock against the USNO Master Clock

This Java applet gets time from our NTP synchronized Web server and compares the result with your clock. This comparison is only done to the nearest second of time. If you only get a blank screen, you may not be allowed to use network sockets to do this.

Note: It can take up to a minute for your system to get a connection during peak hours. Be patient and go have a cup of java while you wait! See this note from Netscape's README file:

            To run Java applets with the Java-enabled version, the
            Navigator needs to be able to load Java class files from a file
            called moz2_0.zip.  This file is included in the distribution,
            but must be moved to any of these directories:

                The current directory
                /usr/local/netscape/java/classes
                /usr/local/lib/netscape
                $HOME/.netscape

            If you were running Java with an earlier beta version of the
            Netscape Navigator, you need to replace your old moz2_0.car file
            or old moz2_0.zip file with the new moz2_0.zip file supplied in
            this distribution.
