19: <h4>Description</h4>
20: <p>This driver supports the Forum Graphic GPS Dating station sold by <a href="http://www.emr.fr/gpsclock.html">EMR company</a>.</p>
21: <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>
22: <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.</p>
