[ntp:questions] 1000s offset between GPS module and NTP servers

Hi.
I've installed a GPS module on a Raspberry Pi and I'm getting 1000ms
offsets between the GPS readings and network NTPs.

Sometimes it will be the GPS which will have 1000ms offset and the NTP
serveurs will have 4-6ms instead.


Anybody has a clue what is going on?


Thank you.
