Pixhawk data log time incorrect

While trying to geo-reference my images in Mission Planner, i noticed the GPS log time stamps were incorrect. The date and time in the 1st column is correct, but the GPS seconds and weeks are wrong - works out to around 1970 somewhere. Not sure if this issue has been dealt with elsewhere.
really struggling to georeference my images because of this.
I had GPS fix for the entire mission.
Please see attached screenshot.
