Hello Hasan,

You are the first person reporting to have tried the Ataris 4 chip with 
Loadstone so it is difficult for us to say for sure what the reason is for 
the inaccurate reporting of the time.

Next time you have Loadstone and your GPS receiver working and you are 
traveling, if you could activate the "Start Logging" feature (Located in 
the File submenu), let it run for a while then "stop logging" that will 
capture the data sent from your GPS receiver.  Then, you will find a file 
called NMEA.log in your Loadstone directory.  If you could E-mail me the 
log I can take a look.  Just  use the address at the top of this message.

Best regards,
