+<h4>Description</h4>
+
+<p>This driver supports the Forum Graphic GPS Dating station sold by <a
+href="http://www.emr.fr/gpsclock.htm">EMR company</a>.
+
+<p>Unfortunately sometime FG GPS start continues reporting of the same 
+date. The only way to fix this problem is GPS power cycling and ntpd
+restart after GPS power-up.
+</P>
+After Jan,10 2000 my FG GPS unit start send a wrong answer after 10:00am
+till 11:00am. It repeat hour value in result string twice. I wroite a small
+code to avoid such problem. Unfortunately I have no second FG GPS unit
+to evaluate this problem. Please let me know if your GPS has no problems
+after Y2K.
