Re: [gpsd-users] date issue gpsd / raspberry pi

[Alexander Stielau]

Hi, talking with myself...

Found a solution. 

The raspberrypi has no rtc.
If set the system date hard to this year (e.g. date -s "2013-06-10") and
the gpsd is started after that, it gets the right time.
I put it into the gpsd startscript.
