fc_sensor_get_time_offset functionality

[necurran]

Is there any documentation about how the fc_sensor_get_time_offset function in libfc-sensor works? Is it expected that this synchronization method would continue to work upon rebooting the apps processor with reboot? How long does it take for the synchronization to take effect?

@necurran It just reads both the apps processor side timestamp and the DSP side timestamp and calculates the difference. It does this 4 time a second in a thread. The thread starts when fc_sensor_initialize is called.
