Where can I find the implementation of the function gps_absolute_time() used in ubx.cpp?

You have to implement it yourself if you want to use the drivers in your project. It's a method that returns a timestamp in microsecond accuracy.
See for example QGC: https://github.com/mavlink/qgroundcontrol/blob/master/src/GPS/definitions.h#L79.
