[gpsd-users] GPS Time Synchronization

[Burton, John]

Hi All!

I have what might or might not be an easy question.

• I have a computer running RedHat Enterprise Linux 7.3 that has GPS reciever attached to it that also provides a PPS signal. This computer is used as a real-time data acquisition system.
• I have configured the computer as described in http://catb.org/gpsd/gpsd-time-service-howto.html to operate as a network clock. This works fine.
• One of the devices I am capturing data from is an INS/GPS system that provides a position and pointing data packet with a GPS timestamp (week since GPS epoch + seconds into the week).
• I also have other devices that I am acquiring data for that I am attaching a timestamp to. I am currently using the boost::chrono::system_clock::now(). 
• I need to have all captured data using the same clock basis for the timestamp.
• How do I get GPS timestamp from my system clock?

John
